 Title: #2839: tests: mark xfail for test_selinux_user_optimized on fed<=28
Action: opened

PR body:
"""
The test TestUserPermissions::test_selinux_user_optimized is
testing the fix for SSSD issue 3819, but the fix is not
available in fedora 28. Hence mark the test as xfail when
executed on fedora <=28 (our nightly tests also run on fed 28).

For full ref: fixed in sssd 1.16.4, Fedora 28 provides
1.16.3-2.fc28 only, while Fedora 29 provides 2.0.0-3.fc29.
