Add kernel-style events for sched_trace_XXX() functionswip-tracepoints

Enable kernel-style events (tracepoint) for Litmus. Litmus events trace the same functions as the sched_trace_XXX(), but can be enabled independently. So, why another tracing infrastructure then: - Litmus tracepoints can be recorded and analyzed together (single time reference) with all other kernel tracing events (e.g., sched:sched_switch, etc.). It's easier to correlate the effects of kernel events on litmus tasks. - It enables a quick way to visualize and process schedule traces using trace-cmd utility and kernelshark visualizer. Kernelshark lacks unit-trace's schedule-correctness checks, but it enables a fast view of schedule traces and it has several filtering options (for all kernel events, not only Litmus').
