1. An assembly for an aircraft, the assembly comprising: an attachment pylon for an aircraft engine;an engine attachment mounted on the attachment pylon to provide a joining between the engine and the attachment pylon, wherein the attachment pylon comprises a primary structure, which comprises an upper spar, a lower spar, and two lateral panels together in a form of a box section, the primary structure being equipped with internal transverse stiffening ribs, andwherein the engine attachment comprises a body located outside the primary structure; andshackles that are articulated on the body and can be articulated on the engine,wherein at least a part of the body of the engine attachment is formed in a single piece with one of the internal transverse stiffening ribs of the primary structure. 2. The assembly according to claim 1, wherein the part of the body of the engine attachment comprises a central beam located outside the primary structure, the body further comprising, at each end of the central beam in a transverse direction of the assembly, a one-piece fitting comprising a first joining portion on which one of the shackles can be articulated and a second joining portion that is fixed to the primary structure and passes into the primary structure. 3. The assembly according to claim 2, wherein the second joining portion is arranged between one of the two lateral panels of the primary structure and a corresponding one of the internal transverse stiffening ribs of the primary structure. 4. The assembly according to claim 2, wherein the first joining portion is in a form of a clevis and the second joining portion is substantially flat. 5. The assembly according to claim 2, wherein the two one-piece fittings are fixed to the central beam, on which one or more of the shackles can be articulated. 6. The assembly according to claim 2, further comprising a device for taking up thrust forces, the device comprising: a support element fixed to an outside of the primary structure;two lateral link rods configured to take up thrust forces; anda spreader articulated on the support element,wherein the two lateral link rods are articulated on two opposite ends of the spreader, respectively, andwherein the two ends of the spreader are flexibly mounted on connecting members that are an integral part of the central beam. 7. The assembly according to claim 6, wherein the support element is arranged in a recess of the central beam. 8. The assembly according to claim 1, wherein the part of the body of the engine attachment is in a form of two extensions of a base of the internal transverse stiffening rib and is located outside the primary structure, the two extensions being spaced apart from one another in a transverse direction of the assembly, and the body of the engine attachment further comprises a main beam fixed to the two extensions, the shackles being articulated on the central beam. 9. The assembly according to claim 8, further comprising a device for taking up thrust forces, the device comprising: a support element fixed to an outside of the primary structure;two lateral link rods configured to take up thrust forces; anda spreader articulated on the support element,wherein the two lateral link rods are articulated on two opposite ends of the spreader, respectively, andwherein two ends of the spreader are flexibly mounted on connecting members that are an integral part of the main beam. 10. The assembly according to claim 9, wherein the support element is arranged between the two extensions of the base of the internal transverse stiffening rib. 11. The assembly according to claim 1, further comprising a device for taking up thrust forces, the device comprising: a support element fixed to an outside of the primary structure;two lateral link rods configured to take up thrust forces; anda spreader articulated on the support element,wherein the two lateral link rods are articulated on two opposite ends of the spreader, respectively. 12. The assembly according to claim 1, wherein the engine attachment is a rear engine attachment and the assembly further comprises a front engine attachment. 13. The assembly according to claim 12, further comprising a device for taking up thrust forces, the device comprising: a support element fixed to an outside of the primary structure;two lateral link rods configured to take up thrust forces; anda spreader articulated on the support element,wherein the two lateral link rods are articulated on two opposite ends of the spreader, respectively, andwherein the rear engine attachment, the front engine attachment, and the device for taking up thrust forces comprise a structure for attaching an engine that comprises an isostatic system for taking up forces. 14. The assembly according to claim 1, wherein the engine attachment comprises first and second lateral half-attachments, wherein the first half-attachment is designed to only take up thrust forces oriented in a vertical direction of the assembly and the second half-attachment is designed to only take up thrust forces oriented in the vertical direction of the assembly and in a transverse direction of the assembly. 15. An aircraft part comprising an assembly according to claim 1, a wing element from which the attachment pylon is suspended, and an engine fixed to the engine attachment. 16. An aircraft comprising at least one assembly according to claim 1. 17. A method for removing an engine fixed by an engine attachment assembly, the method comprising: providing an engine attachment assembly comprising: an attachment pylon for an aircraft engine,an engine attachment mounted on the attachment pylon to provide a joining between the engine and the attachment pylon, wherein the attachment pylon comprises a primary structure, which comprises an upper spar, a lower spar, and two lateral panels together in a form of a box section, the primary structure being equipped with internal transverse stiffening ribs, andwherein the engine attachment comprises a body located outside the primary structure, andshackles that are articulated on the body and are configured to be articulated on the engine,wherein at least a part of the body of the engine attachment is formed in a single piece with one of the internal transverse stiffening ribs of the primary structure, andwherein the shackles have at least two ends; andremoving each of the shackles at at least one of the two ends thereof.
