tracing: Allow histogram triggers to access ftrace internal events
Now that trace_marker can have triggers, including a histogram triggers, the onmatch() and onmax() access the trace event. To do so, the search routine to find the event file needs to use the raw __find_event_file() that does not filter out ftrace events.
