[d-kernel] [PATCH un-def/sisyphus] config: PREEMPT -> PREEMPT_VOLUNTARY

But set default preemption to PREEMPT_VOLUNTARY (which is better for
desktops). PREEMPT_DYNAMIC allows user to control preemption model via
kernel command line (preempt=none,voluntary,full).

You can see runtime preemption model in
  '/sys/kernel/debug/sched/preempt`.
