[vala] codewriter: Do not write (unowned string)[] for constants

    codewriter: Do not write (unowned string)[] for constants
    
    The element type of a constant array is forced to be unowned
    in the parser. Therefore we don't write (unowned string) to avoid
    breaking vapi parsing uselessly with older valac versions.
    
    Fixes bug 732080
