s6-networking: update to 2.7.0.4. Changes:

- Bugfixes.
- If you're using s6-tcpserver-access with IPv6 addresses, you should
  upgrade the s6 package (and rebuild s6-networking if you're linking it
  statically against libs6).
- QoL: s6-tcpclient now does not qualify its argument by default (the
  default changes from -n to -N), to avoid confusion when users give a
  fqdn without a final dot.
