arptables: Support -x/--exact flag

Legacy arptables accepts but ignores the flag. Yet there are remains of
the functionality in sources, like OPT_EXPANDED define and a print_num()
function which acts on FMT_KILOMEGAGIGA flag being set or not. So
instead of mimicking legacy behaviour by explicitly ignoring -x flag for
arptables, just enable the feature for it.
