feat: match any touch screen for libinput, not just Wacom "Finger" devices

Drop the MatchProduct "Finger" restriction from the xorg libinput rule,
leaving only MatchIsTouchscreen "on". MatchIsTouchscreen is set by udev
from hardware capabilities, so it matches finger touch screens of any
brand (ELAN, Goodix, eGalax, Wacom, etc.) while never matching keyboards,
mice, or pen/stylus digitizers (which are tagged as tablets, not
touchscreens). This makes the script work on any touch hardware without
hardcoding device names. Behavior on existing Wacom machines is unchanged
since their finger device matched either way.
