[PATCH RT 12/16] hwlat-detect/trace: Export trace_clock_local for hwlat-detector

[Steven Rostedt]

From: "Steven Rostedt (Red Hat)" <rostedt@xxxxxxxxxxx>

The hwlat-detector needs a better clock than just ktime_get() as that
can induce its own latencies. The trace clock is perfect for it, but
it needs to be exported for use by modules.
