Ignore touchpad contacts that are marked as palms
Some touchpads detect palms in their firmware but continue to report
them, just marking them as palms (e.g. with MT_TOOL_PALM). Since the
Gestures library has no mechanism for marking incoming touches as
pre-detected palms, for now just completely ignore palms reported by the
touchpad.
