ecore_wl2: Send a dmabuf non-immediate create at startup

We use immediate mode dmabuf creation at runtime, but this can result in
clients being killed with no option to fallback if the buffers can't be
consumed by the compositor.

This test should catch when a system can allocate a dmabuf buffer and the
compositor claims to accept dmabuf, but the buffer can't actually be used
for whatever reason.  We'll then use wl_shm at runtime instead of dmabuf.
