User-level uinput permissions

[JPenuchot]

It just came to me that Sunshine emulates devices the same way rkvm does. However Sunshine doesn't require root permissions to do so, but instead requires user permission to access uinput through a udev rule.

It would be very nice to be able to run rkvm as a user as it would be more secure and make configuration much easier. I'll try to figure a way to do it.
