edje/examples: add example of use_systeam_seat_names flagdevs/bdilly/edje_multiseat

Since seat names defined on evas will depend on evas backends,
maybe udev rules, etc, we aren't able to demonstrate it
without manually setting another name for such seats
with efl_input_devices_name_set(). Otherwise
we wouldn't have guarantees it would match
names on EDC.
