[PATCH xf86-input-synaptics v3 2/2] Turn down the default sensitivity for unibody MacBook touchpads

The touchpads are too sensitive by default. A touch is activated when a
finger hovers a millimeter off the device. This change turns down the
default sensitivity so that accidental touchpad interactions are
lessened and pointer interaction accuracy is increased.
