technology: Register a rfkilled technology in technology_add_rfkill

If a technology was rfkilled before connman ran, we need to register
it. If such tech was enabled, technology->device_list will be empty.
We save the state, rfkill unblock the type and exit. When the devices
get unblocked, they are automatically enabled since we saved the enable
state.
