Update autotools root addon to support oreo notification channels

Autotools root add-on doesn't work anymore since Oreo and the notification channels.

It could be interesting if it was possible to have a way to enable/disable notification like before. Even more interesting if single channels could be enabled/disabled.

I since Oreo I tried using autonotification way to disable notification (when I don't need them), but it doesn't work like autotools add-on. I have a mi band 2, and when I stop notification with autonotification, the mi band still vibrate.

With nougat and autotools root add-on, the mi band wouldn't vibrate if the notification was disabled.
