touchpad: re-route trackpoint buttons on the *50 Lenovo series
The laptops on this series have the physical trackpoint buttons back but
wired them up to the touchpad instead of the trackpoint device and they appear
as BTN_0, BTN_1 and BTN_2 for left, right, middle.
The udev hwdb marks these for us with the TOUCHPAD_HAS_TRACKPOINT_BUTTONS tag
[1]. Use that tag to identify them and re-route the events through the
trackstick device after mangling the event codes to represent the actual
buttons.
