Bug 24295: Remove GetTransfers call from C4/HoldsQueue.pm

This patch removes the GetTransfers call from
GetItemsAvailableToFillHoldRequestsForBib instead replacing it with an
inline JOIN in the initial query.

Test plan
1/ Run the holds queue
2/ Check the results
3/ Put one of the items in the holds queue into transit
4/ Run the holds queue again
5/ Check that the results do not contain the item that is in transit
6/ Apply the patch
7/ Run the holds queue again
8/ Check that the results still do not contain the item that is in
transit
