[PATCH 4/7] checkpatch: Mark rcu_read_lock_tasks_trace() and friend BPF-only

[Paul E. McKenney]

The rcu_read_lock_tasks_trace() and rcu_read_unlock_tasks_trace()
functions are intended for use only by BPF.  Therefore, add them to
the list of functions that checkpatch complains about outside of BPF
(and of course, RCU).
