kselftest/arm64: Handle more kselftest result codes in MTE helpers

The MTE selftests have a helper evaluate_test() which translates a return
code into a call to ksft_test_result_*(). Currently this only handles pass
and fail, silently ignoring any other code. Update the helper to support
skipped tests and log any unknown return codes as an error so we get at
least some diagnostic if anything goes wrong.
