Bug 34012: Use template wrapper for tabs: Recalls awaiting pickup

This patch updates the recalls awaiting pickup template so that it uses
the new WRAPPER directive to build tabbed navigation.

Note: this patch includes indentation changes, so check the diff
accordingly.

To test you must have UseRecalls enabled. Apply the patch and go to
Circulation -> Recalls awaiting pickup.

Both the "Recalls waiting" and "Recalls waiting over X days" tabs should
look correct and work correctly.
