plugins: try to create test display in order

Browse source 
When creating the test display for querying capabilites, it try in
certain order: DRM, Wayland and finally X11. GLX nor EGL are tried
since they are either composited with X11 or Wayland.

The reason for this is to reduce the posibility of failure that could
blacklist the plugin.
