[PATCH v3 1/3] test-lib-functions.sh: rename test_must_fail_acceptable()

["Ævar Arnfjörð Bjarmason" <avarab@gmail.com>]

The test_must_fail_acceptable() is really a generic function that can
check if something is a real "git command", e.g. "git", "test-tool"
etc. Let's rename it in preparation for using it in another test
function.
