perf tools: Add tracing_path and remove unneeded functions
There's no need for find_tracing_dir, because perf already searches for
debugfs/tracefs mount on start and populate tracing_events_path.
Adding tracing_path to carry tracing dir string to be used in
get_tracing_file instead of calling find_tracing_dir.
