t7810: use test_expect_code() instead of hand-rolled comparison

This test manually checks the exit code of git-grep for a particular value. In doing so, it intentionally breaks the &&-chain. Modernize the test by taking advantage of test_expect_code() and a normal &&-chain. Signed-off-by: Eric Sunshine <sunshine@sunshineco.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
