When external subcommand support landed, the `lix` binary gave
accidental access to nix3 CLI as well.
This was not the intended effect of this feature, we want to keep `lix`
as a namespace for a new redesign of the CLI (that has not started yet),
while giving that namespace for external subcommands.
To this end, we sever the nix3 CLI connection for the `lix` binary.
Fixes fj#508.
