[tracker] build: don't build-depend on Dia

    build: don't build-depend on Dia
    
    Currently, the gtk-doc generator code in Tracker has a build dependency
    on the Dia application in order to generate some images for the
    documentation; the dependency is not optimal, as Dia is not available
    on all distributions and platforms.
    
    This patch changes the build system to add a specific update-diagrams
    make target to be ran from the ontology docs directory (which updates
    the images), and adds the images themselves under version control.
    
    Fixes GB#688287
