diagnostics: fix IPv6 failures

Veiko Aasarequested to merge
vexch/freedombox:fix-ipv6-failures into master
  • Curl: if an IPv6 zone index is specified, use --interface parameter. This fixes two issues:
    • Curl in Debian Buster doesn't support an IPv6 zone index in URL
    • Curl in Debian Bullseye doesn't redirect properly if a zone index is in URL.
  • Disable IPv6 diagnostics on daemons that don't listen on an IPv6 address: plinth, deluge, transmission

Closes #1519 (closed)
