Bug 25762: Typo in linkitem.tt

Bug 25762: Typo in linkitem.tt

This patch corrects the same typo in two different templates:

’ -> ›

If you want to test beyond examining the patch, apply the patch
and go to Tools -> Rotating collections.

- Add an item to a rotating collection.
- In the browser's title bar (or the tab title if the title bar isn't
  shown) the separator between the rotating collection name and "Add or
  remove items" should be ">" instead of "`"
- Enable the EasyAnalyticalRecords system preference.
- View the detail page for a bibliographic record.
- From the "Edit" menu, choose "Link to host record"
- Check the title bar as you did previously.
