vibrator: fix issue with ledtrig-transient support
There's a problem with enabling the transient trigger in the HAL, that is
the trigger function exports tree properties - activate, state, and
duration which require to be chown'd to system:system during the init
process. Hence, the trigger will be now enabled in the init process and
the HAL will use the "activate" property to determine if the device has
vibrator support via ledtrig-transient.
Test: device vibrates with the driver supports ledtrig-transient
