PR24236, Heap buffer overflow in _bfd_archive_64_bit_slurp_armap

PR 24236
* archive64.c (_bfd_archive_64_bit_slurp_armap): Move code adding
sentinel NUL to string buffer nearer to loop where it is used.
Don't go past sentinel when scanning strings, and don't write
NUL again.
* archive.c (do_slurp_coff_armap): Simplify string handling to
archive64.c style.
