sched: Tweak sched_latency and min_granularity

Allow LAST_BUDDY to kick in sooner, improving cache utilization as soon as
a second buddy pair arrives on scene.  The cost is latency starting to climb
sooner, the tbenefit for tbench 8 on my Q6600 box is ~2%.  No detrimental
effects noted in normal idesktop usage.
