So I checked this.  libssh2 (which is the one we're using) does
not appear to support AF_UNIX for the ssh connection.

We should most likely change over the libssh which is a better
library.  That library does in fact support AF_UNIX connections
through the ssh_socket_unix API, although that's of dubious utility
considering that almost no one runs an sshd listening on a Unix domain
socket.
