This deploys irccat, connected to the #snix channel.
We drop the custom irccat third_party, it's 2 years older than the
latest version in nixpkgs.
The irccat.nix module file contains some of the code present in the TVL
version, it however moves the secrets merging to ExecStartPre=,
given https://github.com/systemd/systemd/issues/19604#issuecomment-989279884
has been fixed for almost a year.
Contrary to the setup there, we don't let irccat connect to ZNC, but
hackint directly (so make use of the secrets logic).
We also drop the network-online.target, and make this overall more
tolerant by using Restart=on-failure.
