rcutorture: Add per-Kconfig fragment boot parameters

Browse Source 
Some Kconfig fragments require rcutorture module parameters to
do optimal testing, for example, a configuration for SRCU would
need rcutorture.torture_type=srcu.  This commit therefore adds a
per-Kconfig-fragment boot-parameter capability.
