xcoff slurp_armap bounds checking
"count * 8 >= size" might overflow, "count >= size / 8" doesn't.
* coff-rs6000.c (_bfd_xcoff_slurp_armap): Don't overflow when
checking symbol count against section size. Guard against strlen
running off end of buffer by allocating one more byte and zeroing.
* coff64-rs6000.c (xcoff64_slurp_armap): Likewise.
