Bug 33736: Add filter for holding library

This patch adds the option to filter the pending bookings to collect report by
items current holding library and defaults to the users logged in library.

We also add the 'Pickup library' column to the report output so staff
know whether the item needs collecting for sending to another library or
for their own.
