If a subtest itself reports success, but the outer testcase fails,
the whole testcase should be reported as a failure. However the status
is recalculated based on the test counts, overwriting the outer test
result. Synthesize a failed test in this case to make sure the failure
is not swallowed.

These patches where previously part of my KUnit UAPI series [0].
I split them out, as they are useful on their own and the KUnit UAPI
series does not actually have a hard dependency on them.
