commit 300e4516f78dbb0a9533749aa84f7e366b023d04 (HEAD -> master)
Author: Scott Moser <smoser@brickies.net>

    tests: fix two recently added tests for sles distro.
    
    test_set_locale_sles and test_set_locale_sles_default were incorrectly
    testing for truth of <distro_object>.uses_systemd rather than calling
    that function and checking its result.
    
    The error was only seen if the system running the tests was not using
    systemd.
