This patch QSKIPs all tests that:
- take to much time sitting in some QTRY_VERIFY or similar before failing
- result in 'not in fullscreen mode' warning (with PASS) - thus completely flaky.
- Where previously determined to not apply to OS X using QT_OS_MAC
The intent is to make the test run-time more reasonable,
both when running the test locally and on the CI system.
Reduce the BLACKLIST - to avoid a 'double elimination' the tests that are skipped now,
should not be BLACKLISTed so that we fix them for good.
