rclone: fix configuration saving

The following error occurs when creating storage configuration in WEBUI:
```
Failed to save config after 10 tries: failed to create temp file for new config: open /etc/rclone/rclone.conf4258227003: permission denied
```

we should set the owner of the parent directory of the configuration
file to rclone.
