wayland/actor-surface: Always set opaque region on alpha-less textures

Browse Source 
Wayland clients using buffers without alpha channel are not expected to
set an opaque region. However, we rely on the opaque region for the fast
painting path in `MetaShapedTexture`.

Thus, make sure to always set an opaque region internally in those cases.
For X11 clients, wo do so already.
