asyncssh API change breaks parsing of config

[martijnwgnr]

The v2.19.0 release of asyncssh has added support for hostname canonicalization. With this change, two new arguments were added to SSHClientConfig.load: canonical and final. We should also pass these parameters in sshfs, because right now the local_user and user are passed in their places, which breaks parsing the config in config.py:
