fix: enable Wacom touch gestures on startup and update start.sh on upgrade

Add xinput call to start.sh so Wacom HID 48E3 touch gesture support is
initialized every time the kiosk starts, not just after lightdm restarts.
Also add start.sh to the upgrade extraction list so it is updated in place
instead of keeping the stale version from the original install.
