compositor-x11: Move synchronization to before-update

Browse Source 
The synchronization must happen no matter the painting, as it in itself
might result in reported damage, making the stage actually painted. Thus
move it out of the "pre-paint" handler, to something explicitly not tied
to the painting itself - ClutterStage::before-update.
