arch linux: weston 5.0.0 not working with nouveau

[Dirk Eibach]

Perhaps I should add, that with rolling back to weston 4.0.0.
everything works fine. So nouveau support must have been broken

So for example, will kmscube draw something on the screen (https://github.com/robclark/kmscube)? BTW, noticed that you are using /dev/dri/card1 in your logs. What's at card0? Note that this kmscube will only open a handle to card0 so you may want to change that and test.
