Ticket 50622 - ds_selinux_enabled may crash on suse
    
    Bug Description: SUSE doesn't have the python-selinux module by
    default, so this tool crashes as it can't find the python
    module for import.
    
    Fix Description: ATtempt to import the library, and on failure
    return false for enabled.
