torture: Simplify code, eliminate RCU_PERF_TEST_RUNNABLE
This commit applies the infamous IS_ENABLED() macro to eliminate a #ifdef. It also eliminates the RCU_PERF_TEST_RUNNABLE Kconfig option in favor of the already-existing rcuperf.perf_runnable kernel boot parameter. Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com>

- You can use /sys/module to manually override this setting.
