Bug 13030: Show waiting hold expiration date for waiting holds on circulation.pl

We should show the date a waiting hold is set to expire for each hold in
the list of waiting holds in circulation.pl

Test Plan:
1) Apply this patch
2) Find a waiting hold for a patron, browser to circulation.pl
   for that patron
3) Set system preference ReservesMaxPickUpDelay to 5
4) Refresh circulation.pl, note the waiting holds now display a
   "waiting until" part with the waiting date plus 5 days
5) Set system preference ReservesMaxPickUpDelay to 0 ( or empty
   string )
6) Refresh circulation.pl, note the waiting hols no longer have a
   "waiting until" line.
