package/unzip: add security patch from Debian

Fix the URL and add a new patch. Quoting changelog [1]:

unzip (6.0-25) unstable; urgency=medium

  * Apply one more patch by Mark Adler:
  - Do not raise a zip bomb alert for a misplaced central directory.
    This should allow Firefox to build again. Closes: #932404.
    Reported by Peter Green. Hopefully CVE-2019-13232 is fixed now.
