Neil Roberts 1f7968e5f9 wayland/x11: Set constraints on the CoglRenderer
When using the Wayland backend this sets a constraint that the
CoglRenderer selects the Wayland EGL winsys.

When a Wayland compositor display is set it now also sets a constraint
that the render should use EGL because only EGL renderers will set up
the required wl_drm global object.

The X11 backend now sets the X11 constraint.
