[mutter] clutter/stage/cogl: Name variable to make coordinate space obvious

    clutter/stage/cogl: Name variable to make coordinate space obvious
    
    The ambiguous "clip" was renamed to "fb_clip_region", as it was called
    at the call site. This should make it more clear that the clip is in
    buffer coordinate space.
