[PATCH 1/2] tests: use shell negation instead of test_must_fail for test_cmp

[Stefan Beller <sbeller@google.com>]

The `test_must_fail` should only be used to indicate a git command is
failing. `test_cmp` is not a git command, such that it doesn't need the
special treatment of `test_must_fail` (which e.g. includes checking for
segfault)
