    Remove fall-back prune_warnings
    
    No one should be using versions of dejagnu without prune_warnings,
    which was available in 1996 (dejagnu-1.3).
    
    binutils/
            * testsuite/lib/binutils-common.exp: Remove fallback prune_warnings.
    gas/
            * testsuite/lib/gas-defs.exp: Remove fallback prune_warnings.
