weston: add --drm-device option for DRM-backend
Developers with testing rigs having multiple graphics cards plugged in
often want to test things on a specific card. We have ways to choose a
card through seat assignments, but configuring that run by run is
awkward.
Add a command line option for opening a specific DRM device.
v2: call it --drm-device instead of --device
