torture: Remove CONFIG_RCU_TORTURE_TEST_RUNNABLE, simplify code
This commit removes CONFIG_RCU_TORTURE_TEST_RUNNABLE in favor of the already-existing rcutorture.torture_runnable kernel boot parameter. It also converts an #ifdef into IS_ENABLED(), saving a few lines of code. Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com>
