package/imagemagick: (security) bump to version 7.0.10-28

- Fix CVE-2019-17547: In ImageMagick before 7.0.8-62, TraceBezier in
  MagickCore/draw.c has a use-after-free.
- Fix CVE-2019-18853: ImageMagick before 7.0.9-0 allows remote attackers
  to cause a denial of service because XML_PARSE_HUGE is not properly
  restricted in coders/svg.c, related to SVG and libxml2.
- Update hash of LICENSE file (update in year with
  https://github.com/ImageMagick/ImageMagick/commit/f775a5cf27a95c42bb6d19b50f4869db265fdaa9)
- Update indentation in hash file (two spaces)
- Switch to github helper - it has always been an autogenerated archive.
