oeqa/core/runner: Handle unexpectedSucesses

Instead of showing:
RESULTS - ptest.PtestRunnerTest.test_ptestrunner - Testcase 1600: UNKNOWN (32.30s)

map unexpectedSuccesses to PASSED and improve the way they're displayed. We
expect/allow ptest runner to fail but if it passes we should handle it correctly.
