wayland: discard non-seat events sent to the seat

The wayland seat event handlers get sent events that
aren't strictly interesting to them (such as events for
hardware devices the seat doesn't support and events for
virtual devices that the seat needs to ignore).

This commit makes sure all uninteresting events get ignored.
