ClutterStageCogl: Don't get buffer damage dirty pixel when not supported

Browse Source 
Now with the existance of offscreen view framebuffers the buffer age
damage regions are only valid if the view in question doesn't doesn't
have an intermediate offscreen. So, for views that doesn't have buffer
age, return the dirty pixel (0,0).
