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.

help
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
boot (you probably don't).
Say N here if you want the RCU performance tests to start only
after being manually enabled via /sys/module.
