LOG: [Offload] Fix not copying the buffer identifier of offloading files

Summary:
This caused an error when copying a file of the same name when multiple
architectures needed the file. The buffer identifier which we use for
the name in `-save-temps` mode would be empty and create in invalid
filename. Copy this correctly now.
