    GIR writer: Fix generation of implemented interfaces
    
    The list of implemented interfaces is expected as
    
        <implements name="Interface1" />
        <implements name="Interface2" />
        ...
    
    by gobject-introspection library (as of 0.6.3), but was written as
    
        <implements>
            <implements name="Interface1" />
            <implements name="Interface2" />
            ...
        </implements>
    
    by Vala.GIRWriter. Note, that vapigen expects the same format as
    gobject-introspection, so it was not able to read vala-written .girs
    before the change and is able to read them properly now.
    
    Fixes bug 584576.
