sched/numa: Update migrate_improves/degrades_locality()
Update the migrate_improves/degrades_locality() functions with knowledge of pseudo-interleaving. Do not consider moving tasks around within the set of group's active nodes as improving or degrading locality. Instead, leave the load balancer free to balance the load between a numa_group's active nodes. Also, switch from the group/task_weight functions to the group/task_fault functions. The "weight" functions involve a division, but both calls use the same divisor, so there's no point in doing that from these functions. On a 4 node (x10 core) system, performance of SPECjbb2005 seems unaffected, though the number of migrations with 2 8-warehouse wide instances seems to have almost halved, due to the scheduler running each instance on a single node.
