HID: multitouch: Add quirk for Hantick 5288 touchpad

Browse Source 
[ Upstream commit b5e65ae557da9fd17b08482ee44ee108ba636182 ]

This device sometimes doesn't send touch release signals when moving
from >=2 fingers to <2 fingers. Using MT_QUIRK_NOT_SEEN_MEANS_UP instead
of MT_QUIRK_ALWAYS_VALID makes sure that no touches become stuck.
