Enable usb_mode udev event for factory mode.

Factory jig internally disconnects only signal cable(in Blue and White) of USB cable.
It makes a strange state.

In general, when the USB cable is disconnected, switch udev event and usb_mode udev event occur.
But, in factory jig case, usb_mode udev event only occurs.

Without luck, data-router.service crashs on factory jig because of one's own problems.
So, we have to restart data-router.service when usb_mode udev event happens.

And, sdbd.service and mtp-response.service also restart as a preventive measure.
