Bug 34610: Update deprecated ProtectSuperlibrarian string

Test:
1. Set ProtectSuperlibrarianPrivileges system preference to Allow only
   superlibrarians
2. Give superlibrarian permissions to a user (User 1)
3. Give catalogue, borrowers, permissions, and staffaccess  permissions
   to a second user (User 2)
3. Login as User 2
4. Go to User 1 permission settings page.
5. Hover over the Select all and Clear all links.
6. Check the message that appears contains
   ProtectSuperlibrarianPrivileges and not ProtectSuperlibrarian
