Only modify `Coordinate Transformation Matrix`
Allow libinput Calibration Matrix to exist as whatever it has set to by default.
This allows for a UDEV rule to be made to set the calibration matrix in cases where
the display and touchscreen do not have the same orientation or pixel sizing.
This now matches the mutter implementation.
