[OSSTEST PATCH 12/14] duration_estimator: Return job column in first query

[Ian Jackson <ian.jackson@xxxxxxxxxxxxx>]

Right now this is pointless since the Perl code doesn't need it.  But
this row is going to be part of a WITH clause soon.

No functional change.

Diffs to two example queries (from the Perl DBI trace):

            SELECT f.flight AS flight,
+                   j.job AS job,
                   f.started AS started,
                    j.status AS status
                     FROM flights f
                     JOIN jobs j USING (flight)
                     JOIN runvars r
                             ON  f.flight=r.flight
                            AND  r.name=?
                    WHERE  j.job=r.job
                      AND  f.blessing=?
                      AND  f.branch=?
                      AND  j.job=?
                      AND  r.val=?
                      AND  (j.status='pass' OR j.status='fail'
                           OR j.status='truncated'!)
                      AND  f.started IS NOT NULL
                       AND  f.started >= ?
                  ORDER BY f.started DESC

            SELECT f.flight AS flight,
+                   s.job AS job,
                    NULL as started,
                    NULL as status,
                    max(s.finished) AS max_finished
                      FROM steps s JOIN flights f
                        ON s.flight=f.flight
                     WHERE s.job=? AND f.blessing=? AND f.branch=?
                        AND s.finished IS NOT NULL
                        AND f.started IS NOT NULL
                        AND f.started >= ?
-                     GROUP BY f.flight
+                     GROUP BY f.flight, s.job
                      ORDER BY max_finished DESC
