[PATCH 13/15] sched,fair: propagate sum_exec_runtime up the hierarchy

Now that enqueue_task_fair and dequeue_task_fair no longer iterate up the hierarchy all the time, a method to lazily propagate sum_exec_runtime up the hierarchy is necessary. Once a tick, propagate the newly accumulated exec_runtime up the hierarchy, and feed it into CFS bandwidth control.
