The version field is a per device information. We have
no guarantees a touchscreen and a tablet device will share
the same version of the firmware (especially if both
firmwares are from different vendors).

If we find an EKR, search for the usb hub of the Cintiq, then find the Cintiq
Pen (or Touch) device and assume that device's product id. This way we end up
in the same device group as the Cintiq.

The newer Wacom Cintiqs have touch devices with a different PID than the pen
device. Use the new libwacom_get_paired_device call where available to pair
the two devices and give them the same device group.
This isn't that important just yet, so no need to force users to update to a
new libwacom version.

Multiple devices plugged into the same USB hub have the same
PHYS path and are assigned to the same group.
Prepend the content of the PRODUCT env to the phys path, this at least ensures
that different devices are never grouped together.

The easiest way to get a device group is by looking at the phys path of the
input device (which looks like usb-0000:00:14.0-1/input1) and dropping the
/inputX bit. The rest is the same for devices that belong together (except on
the Cintiq 22HD Touch).
Ideally we could just take ATTRS{phys} but we can't select substrings to drop
into ENV so we need to do it ourselves. This patch adds a callout that takes a
syspath and prints the mangled path, to be used in LIBINPUT_DEVICE_GROUP.
The rule triggers on any device that has a non-zero phys attribute, this
groups devices like tablets together but also devices like mice with multiple
interfaces.
