sd-bus: allow connecting to the pseudo-container ".host"
    
    machined exposes the pseudo-container ".host" as a reference to the host
    system, and this means "machinectl login .host" and "machinectl shell
    .host" get your a login/shell on the host. systemd-run currently doesn't
    allow that. Let's fix that, and make sd-bus understand ".host" as an
    alias for connecting to the host system.
