tracing: add back the available_events file
The event directory files type and available_types were no longer needed with the new TRACE_EVENT_FORMAT macros, they were deleted. But by accident the available_events file was also removed. This patch brings it back. Reported-by: KOSAKI Motohiro <kosaki.motohiro@jp.fujitsu.com> Signed-off-by: Steven Rostedt <srostedt@redhat.com>
