Bug 20794: Hide holds tab on details when user lacks circulate_remaining_permissions

Bug 20794: Hide holds tab on details when user lacks circulate_remaining_permissions

If a user doesn't have circulate_remaining permissions, but has borrowers:
- checkouts tab is hidden
- details tab is visible
- holds tab on details is visible, but results in an error

The problem is that the svc/holds script requires circulate_remaining_permissions.

To test:
- Create 2 staff users with and without circulate_remaining_permissions
  Both need borrowers permission
- Go to the details tab in a patron's account who has holds
- Verify that you get a datatables error for the staff patron without
  circulate_remaining_permissions
- Apply patch
- Verify that now the holds tab is no longer displayed for this patron
