[PATCH v2 2/5] rcutorture: Remove SRCU-lite scenarios

[Paul E. McKenney]

This commit prepares for the removal of SRCU-Lite by removing the SRCU-L
rcutorture scenario that tests it.

Both SRCU-lite and SRCU-fast provide faster readers by dropping the
smp_mb() call from their lock and unlock primitives, but incur a pair
of added RCU grace periods during the SRCU grace period.  There is a
trivial mapping from the SRCU-lite API to that of SRCU-fast, so there
should be no transition issues.

[ paulmck: Apply Christoph Hellwig feedback. ]
