[PATCH v2] remote: Refuse connecting to remote socket

[Michal Privoznik <mprivozn@xxxxxxxxxx>]

If users wants to connect to remote unix socket, e.g.
'qemu+unix://<remote>/system' currently the <remote> part is ignored,
ending up connecting to localhost. Connecting to remote socket is not
supported and user should have used TLS/TCP/SSH instead.
