[MachO] Replace macho-dump with llvm-readobj in tests

[davide]

Summary

The main reason why I brought up this review is understanding if the format provided by llvm-readobj -r is good enough for us.
macho-dump just dumps the raw words for each reloc while readobj prints something more human readable after processing.
I personally like llvm-readobj format a lot better, but I would like to hear other opinions. An alternative would be that of introducing llvm-readobj --dump-raw-reloc-macho (maybe with a less cumbersome name), but I don't think it's really needed.

LGTM.
