To better reflect the actual test plan status. If 0 tests were run, it doesn't
really make sense to say that the test plan passed, rather it was skipped since
nothing was run. So with this change, if there's a regression that prevents the
soundcard driver from even probing, the result won't be "pass", but "skip", and
the reason 'No soundcard available' will be in the logs.
