Remove all the "factory reset" stuff
    
    From reading BZ1290659 [1] it sounds like the ostree issue was resolved
    by using /etc/selinux as the store root instead of /var/lib/selinux so I
    believe the /usr/share/selinux redundant files are no longer needed.
    Also remove all other leftovers of the factory reset thing...
