Bug 37152: Aquisitions basket and OPAC suggestion deletion should use the op cud-delete

Both deleting a basket in Aquisitions and deleting a suggestion in the OPAC
take care of the confirmation in a javascript modal, rather than having a
whole separate page for confirmation, so they should be using the op
cud-delete rather than either cud-delete_confirm (which shouldn't ever be
used) or delete_confirm (which they aren't doing, they already confirmed).

Test plan:
1. There's no wrong behavior to see, so apply patch and restart_all
2. Aquisitions - Vendor search for My Vendor - Click My Basket
3. Click Delete basket, in the popup again Delete basket
4. Click Show baskets for vendor My Vendor and verify the basket is gone
5. OPAC - Your account - Purchase suggestions
6. Create a suggestion, then click the checkbox for it, Delete selected,
   confirm
7. Verify the suggestion was deleted
