drm-lease: Enable DRM render node on R-Car
When using DRM lease, wayland clients applications must
be able to create an EGL context without DRM authentication.
The latest R-Car OpenGL driver, can do this when the R-Car
display driver must provides a render node.
Enable the rcar-du render node and allow it to allocate of
scanout buffers.
Bug-AGL: SPEC-3730
