Bug 26795: Remove the use of jquery.checkboxes plugin from ILL pages

This patch removes the inclusion of the jquery.checkboxes plugin from
two staff interface ILL pages where the plugin is unused.

To test you need at least one patron with some ILL requests.

- Apply the patch and locate a patron with ILL requests.
- Click the "ILL requests history" tab.
- Confirm that the table of requests has no checkboxes.
- Choose "Ill requests" from the "More" menu in the header.
- Confirm that the table of requests has no checkboxes.
