Bug 23987: Use src=CATALOGUING for edition/deletion in batch from items table

There are 2 ways to land in batchMod from the detail page of a bib
record: from the Edit menu, and the action buttons on top of the items
table.

We want the same behavior for both and so use src=CATALOGUING
It will make batchMod to behave identically for the "return" button
