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.

- This option provides a way to build the RCU performance tests
- directly into the kernel without them starting up at boot time.
- You can use /sys/module to manually override this setting.
- This /proc file is available only when the RCU performance
- tests have been built into the kernel.

- Say Y here if you want the RCU performance tests to start during

- Say N here if you want the RCU performance tests to start only
- after being manually enabled via /sys/module.
