Subject: [PATCH] fix: add xorg.conf.d Wacom touch config so driver starts in
 touch event mode

Without /etc/X11/xorg.conf.d/99-wacom-touch.conf the Wacom driver initialises
the finger touch device in pointer emulation mode (generating RawButtonPress/
RawButtonRelease/RawMotion). Electron never sees TouchBegin/TouchEnd events so
touchstart/pointerdown(touch) never fire in the renderer.

Setting Option "Gesture" "on" and Option "Touch" "on" at the driver level means
the device initialises in XI2 touch mode on every X server start, regardless of
any post-init xinput set-prop calls.

Added to both fresh install (step 18) and upgrade function.
