    x11: Fix touchpad detection
    
    Commit 79849ef1d5fff9acd310cd68d59df0c7cf2cb28f had a typo in the
    device property format check. This property is formated in 8-bit
    items, not 32-bit.
    
    This went unnoticed till now because some touchpads were still being
    detected as such due to a second check below:
    
          else if (strstr (name, "touchpad") != NULL)
            source = CLUTTER_TOUCHPAD_DEVICE;
