Currently, most of the rcutorture scenarios do not explicitly set the CONFIG_PREEMPT_LAZY Kconfig option one way or the other. This can result int "improperly set" diagnostics from kvm.sh, which indicate that the scenario in question isn't testing what it is supposed to test, which can result in missed bugs. This commit therefore explicitly sets CONFIG_PREEMPT_LAZY as needed.
