Tweak OpenMP parameters for lightbaker
On higher threadcount systems this allows for better utilization. On my
16 thread box CPU use goes from 10 - 11 threads to a steady 15 threads
on the Sponza scene.
Baking time goes from ~10:00 to ~07:30 for me. On lower threadcount
systems I expect some improvement also but likely a little less.
