A fix for 'ar tv' and 'ar x'

This is similar to bug 13534 but with 4+GB files and only impacts 32bit
platforms.

$ ls -l file4G

The od command shows that the ar archive was created correctly. However 'ar tv'
and 'ar x' think it is a 100MB file which is incorrect.

This happens because print_arelt_descr(), print_contents() and extract_file()
use 32bit size_t variables instead of bfd_size_type ones.
