tracing: Have HIST_TRIGGERS select TRACING
commit 7ad8fb61c4abf589596f0a4da34d987471481569 upstream.
The kbuild test robot reported a compile error if HIST_TRIGGERS was
enabled but nothing else that selected TRACING was configured in.
HIST_TRIGGERS should directly select it and not rely on anything else
to do it.
