rcutorture: Add CONFIG_PREEMPT_DYNAMIC=n to tiny scenarios

With CONFIG_PREEMPT_DYNAMIC=y, the kernel builds with CONFIG_PREEMPTION=y because preemption can be enabled at runtime. This prevents any tests of Tiny RCU or Tiny SRCU from running correctly. This commit therefore explicitly sets CONFIG_PREEMPT_DYNAMIC=n for those scenarios. Signed-off-by: Paul E. McKenney <paulmck@kernel.org>
