tracing: Use CONFIG_PREEMPTION
CONFIG_PREEMPTION is selected by CONFIG_PREEMPT and by
CONFIG_PREEMPT_RT. Both PREEMPT and PREEMPT_RT require the same
functionality which today depends on CONFIG_PREEMPT.
Switch the conditionals in the tracer over to CONFIG_PREEMPTION.
This is the first step to make the tracer work on RT. The other small
tweaks are submitted separately.
