package/suricata: security bump to version 4.1.5

- Drop second patch (already in version)
- Add libmaxminddb optional dependency and use --disable-libgeoip to prefer
  maxminddb over geoip, see:
  https://github.com/OISF/suricata/commit/d29072647fa479eb748357a5a75f1ac4206a2cff
  https://github.com/OISF/suricata/commit/c55226b7126079d78e4bf5c6fc290242001954a6
- Disable sphinx-build (to avoid a build failure)
- This release fixes a number of issues found in the 4.1 branch. Some of
  the issues are security issues, so upgrading is highly recommended.
