Comment 7 for bug 1768784

Fixed the test-apparmor.py qrt script to always apply the longpath test fix that makes sure path_max is writable before testing, and if not, XFAILs the test. This is in qrt commit https://git.launchpad.net/qa-regression-testing/commit/?id=99de7d240dc3e96a9b03cf9924c43f1aa0bd3c40 .

Thanks!
