refscale: 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 refscale scenarios
to CONFIG_PREEMPT_LAZY.
