sched: Make set_*_buddy() work on non-task entities
Make set_*_buddy() work on non-task sched_entity, to facilitate the use of next_buddy to cache a group entity in cases where one of the tasks within that entity sleeps or gets preempted. set_skip_buddy() was incorrectly comparing the policy of task that is yielding to be not equal to SCHED_IDLE. Yielding should happen even when task yielding is SCHED_IDLE. This change removes the policy check on the yielding task.
