rcu: Catch rcutorture up to new RCU API additions

Now that the RCU API contains synchronize_rcu_bh(), synchronize_sched(),
call_rcu_sched(), and rcu_bh_expedited()...

Make rcutorture test synchronize_rcu_bh(), getting rid of the old
rcu_bh_torture_synchronize() workaround.  Similarly, make rcutorture test
synchronize_sched(), getting rid of the old sched_torture_synchronize()
workaround.  Make rcutorture test call_rcu_sched() instead of wrappering
synchronize_sched().  Also add testing of rcu_bh_expedited().
