wayland: use wl_output v4 for --fs-screen-name

Browse Source 
In wayland 1.20.0, a couple of new events, name and description, were
added to the interface. Description is not particularly useful, but name
returns back nice names for the output like "DP-1" and so on. It makes
sense to use these for fs-screen-name and prefer them over the model
name (old way of doing it) if they are available. The only problem is
that 1.20.0 is pretty new so old distros aren't going to have it anytime
soon. Deal with this by adding some defines.
