cgroup: avoid the unnecessary list_add(dying_tasks) in cgroup_exit()
cgroup_exit() needs to do this only if the exiting task is a leader and it
is not the last live thread. The patch doesn't use delay_group_leader(),
atomic_read(signal->live) matches the code css_task_iter_advance() more.
cgroup_release() can now check list_empty(task->cg_list) before it takes
css_set_lock and calls ss_set_skip_task_iters().
