    mouse: Don't enable two-finger scrolling based on width
    
    Reverts part of 109b36919921d757b93b91e8082620078608967e
    
    Good idea in principle, albeit the hardware gets in our way. In
    synaptics 1.4 two-finger emulation was enabled by default on devices
    that reported finger width but had to since revert this. The hardware
    doesn't really separate width and pressure, so a hard tap off a finger
    gives a high width, a wide finger gives a high pressure on light
    touches. We got spurious right-click presses when two-finger
    emulation was enabled.
    
    Now we have the control-center providing a checkbox for two-finger
    emulation but it doesn't enable emulation, which to the users appears as if
    two-finger scrolling is broken
    (https://bugzilla.redhat.com/show_bug.cgi?id=738123).
    
    We now disable the checkbox again for hardware that doesn't do two-fingers.
    it's not reliable and we're likely to see further bugs when the spurious right
    clicks take effect
