Bug 35547: Show public "staff only" lists in addbybiblionumber.pl

Bug 35547: Show public "staff only" lists in addbybiblionumber.pl

When adding an item to a list from catalogue/detail.pl, we can see the
latest 10  public lists. If all those lists are set as "staff only" for
"Allow changes to contents from" they will not show up in the
addbybiblionumber.pl popup. This is because the query in the popup does
not look for "staff only" lists while the "Add to list" button does.

Test plan:
1) Create 11 "staff only" lists as staff member A
2) Log in as staff member B
3) Find a record, click the "Add to list" button, note you can see lists
   2 through 11 here
4) In the pulldown, choose the "More lists" option
5) Note those lists are not visible in the "Choose list" pulldown under
   "Select an existing list"
6) Apply this patch
7) Restart all the things!
8) Click the "More lists" option again
9) Those lists should now be in the pulldown!
