[libunwind] [libunwind] Stop installing the mach-o module map (PR #105616)

[Ian Anderson via cfe-commits]

https://github.com/ian-twilightcoder created https://github.com/llvm/llvm-project/pull/105616

libunwind shouldn't know that compact_unwind_encoding.h is part of a MachO module that it doesn't own. Delete the mach-o module map, and let whatever is in charge of the mach-o directory be the one to say how its module is organized and where compact_unwind_encoding.h fits in.
