Bug 36511: Some scripts missing a dependency following Bug 24879

These files needed the addition of 'use C4::Auth qw( check_cookie_auth
);'.

To test, apply the patch and restart services.

- If necessary, enable the LocalCoverImages system preference.
- Open the browser console and then the "Network" tab. You can click
  "Images" to filter for the correct kind of request.
- Perform a catalog search. After the search has loaded, check that
  there are no 500 errors in the Network tab.

- Go to Cataloging -> Label creator.
- If necessary, create a label batch and add some items.
- Export your batch and test both the "Download as CSV" and "Download as
  XML" links. Both should trigger the correct download.

- Go to Serials -> Claims, and select a vendor with late issues.
- Select all late issues and click "Download selected claims" at the
  bottom of the page.
- Your CSV file should download correctly.

The file acqui/check_uniqueness.pl has been corrected as well but I'm
not sure how to test it!
