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.
