    stop hald-addon-dell-backlight if needed kernel module isni't loaded
    
    Currently the hald-addon-dell-backlight is running also if the
    needed dcdbas kernel module is not loaded. In this case it provide
    the brightness interface with only one brightness level, which is
    useless.
    
    Simply exit the addon if the kernel module is missing to prevent
    to have a useless interface for brightness.
