bug 2274: correcting call to new interface of overdue_notices.pl

I changed the interface to overdue_notices.pl at the last moment and forgot to correct one call to it.
This corrects circ/overdue.pl to call misc/cronjobs/overdue_notices.pl with the correct parameters.

Even better would be to move most of the code from overdue_notices.pl to a method somewhere
that both of these programs could call. It's inappropriate to call a cronjob from one of our CGIs.
