touchpad: require at least 3 events before enabling trackpoint palm detection

Some trackpoints, notably the one on the Lenovo T460s have a tendency to send
the odd event even when they're not actually used. Trackpoint events trigger
palm detection (see 0210f1fe) and thus effectively disable the touchpad,
causing the touchpad to appear nonresponsive.

Fix this by requiring at least 3 events from a trackpoint before palm
detection is enabled. For normal use it's hard enough to trigger a single
event anyway so this should not affect the normal use-case.
