rcutorture: Update due to x86 not supporting none/voluntary preemption
As of v7.0-rc1, architectures that support preemption, including x86 and arm64, no longer support CONFIG_PREEMPT_NONE or CONFIG_PREEMPT_VOLUNTARY. Attempting to build kernels with these two Kconfig options results in .config errors. This commit therefore switches such rcutorture scenarios to CONFIG_PREEMPT_LAZY. Signed-off-by: Paul E.
