grep: add a test helper function for less verbose -f \0 tests

Add a helper function to make the tests which check for patterns with \0 in them more succinct. Right now this isn't a big win, but subsequent commits will add a lot more of these tests. The helper is based on the match() function in t3070-wildmatch.sh. Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
