clightning: add announce-tor
From the clightning manpage:

autolisten=BOOL By default, we bind (and maybe announce) on IPv4 and
IPv6 interfaces if no addr, bind-addr or  announce-addr options  are
specified. Setting this to false disables that.

We already set bind-addr by default, so autolisten had no effect.
Therefore, this commit replaces autolisten with the more granular
announce-addr option.

For now we are Tor-only, so we only need to announce our hidden service
to accept incoming connections. In the future, we can add clearnet
connectivity with `addr` and route connections into our netns with NAT.

lnd: only enable bitcoind zmqpub if lnd.enable
In conjuction with secure-node.nix, this sets sane
RestrictAddressFamilies unless lnd is enabled. Before, we were
constantly exposing unnecessary Address Families, not just when lnd is
enabled.

However, zmqpub* must always be enabled for lnd, even when used
outside of secure-node.nix, so we make this change in the lnd module.
