    Bug 574351 - Add --pkg-export option
    
    We need to differentiate between --pkg options we use to parse
    ourself, and --pkg-export which are needed for library consumers.
    
    When introspecting a library we won't necessarily have the
    pkg-config file built, so add a --pkg-export line so library
    authors can explicitly make the .gir -> pkg-config association.
