  [ELF] -Map --why-extract=: print despite errors

Fix https://github.com/llvm/llvm-project/issues/53073

In case of a relocation error, GNU ld's link map includes
the archive member extraction information but not output sections.

Our -Map and --why-extract= are currently no-op in case of an error.
This change makes the two options work.
