laters: Use clutter_stage_schedule_update() instead of timeline

Browse Source 
The MetaLater functionality needs to make sure an update is scheduled so
that it can run its callbacks etc. This used a ClutterTimeline (which is
an object more or less meant to drive animations markers, frames etc)
just to keep the master frame clock running. We're moving away from a
single master clock, so just schedule updates directly instead, with the
newly exposed API.
