    Only use mtdev for multitouch devices
    
    mtdev uses a chunk of memory per device (~41kB), mainly for for its
    internal event buffers. The average box these days can easily have 10
    devices, but only few of those are multitouch. So check if we have
    ABS_MT_POSITION axes and only create an mtdev instance if we do.
    
    If a device has multitouch axes but not x/y, we will ignore events from this
    device now.
