[PATCH 0/5] t: replace incorrect test_must_fail usage (part 6)

The overall scope of these patches is to replace inappropriate uses of test_must_fail. IOW, we should only allow test_must_fail to run on `git` and `test-tool`. Ultimately, we will conclude by making test_must_fail error out on non-git commands. An advance view of the final series can be found here[1].

This is the sixth and final(!) part. It cleans up instances of `test_must_fail` that were introduced since the effort began. In addition, it finally flips the switch and makes test_must_fail only allow a whitelist of commands.

This series is based on the merge of 'master' and 'dl/test-must-fail-fixes-5'. In addition, this series was tested by merging with 'seen~1' (to ignore the reftable failures) to ensure no in-flight topics will require more changes.

The first part can be found here[2]. The second part can be found here[3]. The third part can be found here[4]. The fourth part can be found here[5]. The fifth part can be found here[6].
