bsdgrep: switch to libregex for GNU_GREP_COMPAT

libregex is incomplete, but it's a bit less buggy than the in-base
libgnuregex and mostly OK.

While here, rename -DIWTH_GNU -> -DWITH_GNU_COMPAT; the option implies
that we're compatible with the GNU counterpart, not that we're including GNU
anything.
