[PATCH libinput] udev: add quirk for Chalkboard Electronics HID Touchscreen

[Matt Porter]

The Chalkboard Electronics HID Touchscreen is classified as
a tablet device by systemd udev because it has BTN_TOOL_PEN
support. It also reports a resolution of 0 for both X and Y
axes in absinfo. This causes libinput to reject it as an
invalid tablet device.

This quirk reclassifies the device as a touchscreen which
allows it to be added as a valid input device.
