MetaBackgroundActor: remove GLSL shader support

That code made sense when MetaBackgroundActor was just painting a rectangular
texture. Now that it paints multiple primitives with different pipelines and
attributes it doesn't anymore, so users should go back to ClutterEffect and
FBO redirection (which should be by now a lot faster)
