Supress physical clicks w/o fingers for Grunt

This patch diables "Zero Finger Clicks" for Grunt variants
(Careena/Barla/Mordin) which refers to CL:456122
to suppress the ghost events.

So there will be no fingers action on the UI layer
if there is no physical finger touch.

TEST=cros_workon-grunt start chromeos-base/gestures-conf
     emerge-grunt chromeos-base/gestures-conf
     cros deploy --board=grunt ${IP} chromeos-base/gestures-conf
     shake device intensively to check whether there is false click
     event on the UI layer such as online painting app
