t4124: only mark git command with test_must_fail 

The test_must_fail function should only be used for git commands since
we should assume that external commands work sanely. Since apply_patch
wraps a sed and git invocation, rewrite it to accept an `!` argument
which would cause only the git command to be prefixed with
`test_must_fail`.
