rcutorture: Remove the "rcu_bh" and "sched" torture types

Browse Source 
Now that the RCU-bh and RCU-sched update-side functions are simple
wrappers around their RCU counterparts, there isn't a whole lot of point
in testing them.  This commit therefore removes the "rcu_bh" and "sched"
torture types from rcutorture.
