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.

help
This option provides a way to build the RCU torture tests
directly into the kernel without them starting up at boot
time. You can use /proc/sys/kernel/rcutorture_runnable
to manually override this setting. This /proc file is
available only when the RCU torture tests have been built
into the kernel.
Say Y here if you want the RCU torture tests to start during
boot (you probably don't).
Say N here if you want the RCU torture tests to start only
after being manually enabled via /proc.
