[PATCH] virnetsocket: pass HOME and XDG_RUNTIME_DIR to ssh

[Дамјан Георгиевски]

openssh supports environment variable expansion in its ssh_config
file[1]. These two environment variables can be used to
expand paths for ssh sockets and other files.

Ex.
```
Host *
 ControlMaster auto
 ControlPath ${XDG_RUNTIME_DIR}/ssh-%C.ctl
 IdentityAgent ${XDG_RUNTIME_DIR}/ssh-agent.socket
```
