Trying to use Zink with the DRM winsys is problematic at best. In theory all the pieces should be there but there are bugs around synchronization, etc. This copies the current behavior of X11 which also refuses to initialize DRM on Zink. This is particularly important for Nouveau users which are getting Zink via the loader returning "zink" for get_driver_for_fd(). On Wayland today, we go ahead and load zink and attempt to use the DRM EGL paths, which are broken. On X11, it fails to load the driver and then the EGL device initialization code re-tries with zink which succeeds. Because the second try is using Zink from the start, it's equivalent to if the user had set MESA_LOADER_DRIVER_OVERRIDE=zink and they get the kopper path, which is more reliable. This absolutely not what we want because it means we don't load the driver the loader requested and are dependent on fallback paths to get a driver loaded at all. However, the real solution in https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/36014 is too complex to backport.
