clutter: Reduce default clutter_max_render_time_constant_us to 1000

Browse Source 
Now that dynamic max render time uses a new algorithm and takes dispatch
lateness into account, this seems worth a shot. We'll see how it works
out in the wild.

The net result compared to before these changes is still slightly higher
(by ~0.5 ms) minimum latency for me, as measured by
weston-presentation-shm. It should be less vulnerable to frame drops
though.
