Use environment variable for the socket.

Browse Source 
The default behavior is to create a socket file at /tmp/guestfs-inspect.sock.
If XDG_RUNTIME_DIR is set, that will be used instead of /tmp.

One could instead specify GUESTFS_INSPECT_ENDPOINT, which requires the full endpoint, as specified by: https://libzmq.readthedocs.io/en/zeromq3-x/zmq_connect.html

You will likely want to use ipc://, but you can probably use tcp:// or (e)pgm:// if that is appropriate.
