glx-tfp: Don't include glx.h

Since the implementation of ClutterGLXTexturePixmap has nothing GLX
specific about it (it is simply layered on top of
ClutterX11TexturePixmap) we don't need to include glx.h. Removing this
include also means that the code can be built for compatibility against
GLES drivers.
