Bug 32688: Convert recalls awaiting pickup tabs to Bootstrap

This patch updates the recalls awaiting pickup template
(recalls_waiting.tt) to replace a set of jQueryUI tabs. They are
converted to Bootstrap in order to complete Bug 29226.

To test, apply the patch and make sure the "UseRecalls" system
preference is enabled.

- Go to Circulation -> Recalls awaiting pickup.
- You should see two tabs, "Recalls waiting" and "Recalls waiting over X
  days."
- The tabs should look correct and work correctly.
