Subject: [PATCH] hydra-notify: enable IPv6 support

HTTP::Server::PSGI uses the `ipv6` flag to decide between
  `IO::Socket::INET` and `IO::Socket::IP`
  (https://metacpan.org/dist/Plack/source/lib/HTTP/Server/PSGI.pm#L80-84)
and (from IO/Socket/IP.pm):
> C<IO::Socket::IP> - Family-neutral IP socket supporting both IPv4 and IPv6
so setting the `ipv6` flag makes it support both IPv4 and IPv6.

Fixes #1394
