Purge GuestMouse support.
Guest mouse dates back to quite a while ago, hasn't been tested for ages and the current synaptics interface guide claims the bit that we used to check if guestmouse is available is "reserved for future use. The host should ignore the values of reserved bits when reading the capability bits." Signed-off-by: Peter Hutterer <peter.hutterer@who-t.net>
