uek-rpm: enable CONFIG_PREEMPT_VOLUNTARY

Without this option, the kernel with DTrace enabled will fail due to a lack of definition of voluntary
preemption configuration. We discovered that config file in 4.14.14 for aarch64 (config-4.14.x-aarch64),
the default preemption configuration is off entirely.
