Bug 3886: Fix mismatch of required permissions for printing slips

- Print summary (summary-print.pl)
- Print quick slip (printslip.pl)
- Print slip (printslip.pl)
- Print overdues (print_overdues.pl)

Perl scripts all require circulate_remaining_permissions, while
in the template we were checking for edit_borrowers.

Now the print pull down will only be visible if the patron has
circulate or circulate_remaining_permissions.

To test:
- Verify that printing the listed slips works for staff users
  with either circulate or circulate_remaining_permissions
  and without edit_borrowers.
