    When generating for C#, fix the DllImport name
    
    By default the DllImport line in the generated bindings will use the
    name of the SWIG module while the actual name of the library created
    will be based on what is passed to swig_add_module. The tells SWIG to
    use the actual name of the library in the DllImport line.
