recordmcount: Clarify what cleanup() does
cleanup() mostly frees/unmaps the malloc'd/privately-mapped
copy of the ELF file recordmcount is working on, which is
set up in mmap_file(). It also deals with positioning within
the pseduo prive-mapping of the file and appending to the ELF
file.
Split into two steps:
mmap_cleanup() for the mapping itself
file_append_cleanup() for allocations storing the
appended ELF data.
Also, move the global variable initializations out of the main,
per-object-file loop and nearer to the alloc/init (mmap_file())
and two cleanup functions so we can more clearly see how they're
related.
