Add run_id to final_report from LocalRecorder (openai#1452)

(Not an eval)

The `final_report` log line currently doesn't include the `run_id`,
which means that if we want to work out which run it belongs to, we have
to look at the `run_id` of other log lines in the same file. This makes
it a bit harder to work with the logs, and as far as I can tell there's
no downside to including the `run_id`.
