Input: add BTN_TOOL_QUINTTAP for reporting 5 fingers on touchpad
"4-finger scroll" is a gesture supported by some applications and operating systems. "Resting thumb" is when a clickpad user rests a finger (e.g., a thumb), in a "click zone" (typically the bottom of the touchpad) in anticipation of click+move=select gestures. Thus, "4-finger scroll + resting thumb" is a 5-finger gesture. To allow userspace to detect this gesture, we send BTN_TOOL_QUINTTAP.
