[PATCH xf86-input-synaptics] Turn down the default sensitivity for MacBook touchpads

[Chase Douglas]

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.
