Peter Hutterer d31b5a1ccf eis: only queue a seat bind event if the caps change
This triggered an internal bug message in test_ei_seat_bind_unbind_immediately.

If a client unbinds all capabilities this triggers an EIS_SEAT_BIND with
zero caps. peck would call eis_seat_remove() which calls eis_seat_drop().
That queued another EIS_EVENT_SEAT_BIND with zero capabilities, leading
peck to call eis_seat_remove() again on an already removed seat.
