perf evsel: Add 'immediate' option

Add an option to cause a selected event to be enabled immediately when
configured by perf_evsel__config().

This is needed when using the sched_switch tracepoint to follow object
code execution.  By having sched_switch enabled immediately the first
sched_switch event precedes the start of other tracing.
