Bug 10452: make AllowHoldsOnDamagedItems control using damaged items to fulfill holds

AllowHoldsOnDamagedItems will stop item-specific holds from being placed
on damaged items, but does not stop Koha from using damaged items to
fill holds. This seems like incorrect behavior.

Test Plan:
1) Set 'AllowHoldsOnDamagedItems' to "Don't Allow"
2) Pick an item, set it to damaged
3) Place a bib-level hold on this item's record
4) Scan the item though the returns system
5) Koha will ask to use this item to fill the hold, click "ignore"
6) Apply this patch
7) Repeat step 4
8) Koha will not ask to use this item to fill the hold
