oeqa/runner: Ensure we don't print misleading results output
The current code assumes if something isn't a failure of some
kind, it was a pass. When test case IDs weren't matching, this lead
to very confusing output where things would fail, then be listed as
passing.
This adds code to track successes, ensuring we don't end up in this
position again with unmatched entries being listed as UNKNOWN.
