[PATCH] D96308: [llvm-objcopy] Avoid rename if input filename = output filename

[Fangrui Song via Phabricator via llvm-commits]

MaskRay added a comment.

Confirmed with phosek that `--build-id-link-{input,out}` is no longer used by Fuchsia, so I suspect the two options are not used by anyone now. However, I need to special case them to avoid breaking `build-id-link-dir.test`
Similarly, the `-` special case is needed to prevent breaking tests.
