Use the `LISTEN_FDS` mechanism to use pre-opened sockets.
Especially for `wasm32-wasi` there is no other way to get access to sockets,
than to use pre-opened sockets.
Because `wasm32-wasi` does not yet return `TcpListener::local_addr()`, an
unspecified IP address and port will be returned and displayed.
