Changed DeviceDataManagerX11 to use xinput1 for low resolution scroll devices

I added functionality to DeviceDataManagerX11 that uses xinput1 for
devices that gain no extra precision from using xinput2. This means that
for devices that don't ouput two scroll events on focus of a window
(which seems to be the case for classic mice driven by evdev) we don't
experience a missed scroll event on focus.
