The rfkill service waits for rfkill device initialization as reported by udev_device_is_initialized(), and if that is never reported it might dead-lock. However, udev never reports completed initialization for devices that have no properties or tags set. For some rfkill devices this might be the case, in particular those which are connected to exotic busses, where path_id returns nothing. This patch simply sets the SYSTEM_RFKILL property on all rfkill devices, to ensure that udev_device_is_initialized() always reports something useful and we don't dead-lock. Fixes: #2745
