Cherry Zhang 8cd35e00bd cmd/internal/buildid: update Mach-O code signature when rewriting buildid
As the code signature contains hashes of the entire file (except
the signature itself), rewriting buildid will invalidate the
signature. This CL makes it regenerate the signature when
rewriting the buildid. It only does it when the file already has
a code signature, with proper size (darwin/arm64 binaries
generated by the Go linker should have).

Updates #38485, #42684.
