evdev: disable ABS_MT_TOOL_PALM on the Lenovo X1 Carbon 6th gen

This device randomly decides that a touch is now a palm, based on
the moon phase, the user's starsign and possibly what the dog had for
breakfast. Since libinput assumes that a touchpad that labels a touch as palm
has reasons to do so, let's unassume this for this device by disabling that
axis altogether and relying on the touch pressure only.
