Bug 15386: Checkout / patron pages: Hide menu items leading to 404 pages

Some of the menu items on patron / Checkout related pages lead to a 404 page
depending on the permissions. This patch hides them as appropriate.

To test:

- For a staff member A, set permission 'borrowers' only (+ 'catalogue')
- Log in as A
- Search a patron and display details
- Verify that none of the menu items at the left lead to the 404 page

- For a staff member B, set permission 'circulate_remaining_permission'
  only (+ catalogue)
- Log in as B
- Go to Circulation > Checkout, search a patron
- Click menu items at the left, some of them lead to the 404 page
- Verify that none of the menu items at the left lead to the 404 page

- Do the same for a staff member C with both permissions set
- Verify that menu items appear as expected

Amended patch: I have remove the double if
CAN_user_circulate_circulate_remaining_permissions statement (and group
block into one). And also remove unecessary change ('IF a IF b' instead
of existing 'IF a && b')
