Reorder CNI config to set options before consumers

The `WithLoNetwork` and `WithConfFile` options consume the
`WithPluginDir` and `WithInterfacePrefix` settings, so they must come
first.

This fixes the issue that the provided plugin directory was not used for
the provided configuration file. This would have been more visible, but
the default `InterfacePrefix` is already "eth".
