ffbs-parker-nodeconfig: firewall: Allow respondd from all internal addr

This firewall rules make sure, that respondd is only accessible from
inside the Freifunk network (client network or VPN) - but not from other
interfaces (e.g. `br-wan`).

While we were only using it for Freifunk Braunschweig the `src_ip`
limitation did not really matter:
Per definition these are the only IPv6 addresses on these interfaces
anyway.

But while preparing this tooling for a wider use we should rethink this
decision.
There is no need to limit access to a specific IPv6 range, as long as
the requests are still coming from the inside.
