libinput-device: use the discrete axis value for wheel events

libinput < 0.8 sent wheel click events with value 10. Since 0.8
the value is the angle of the click in degrees but it now provides
the click count as separate value. To keep backwards-compat with
existing clients, we just send multiples of the click count.
