    build-tools: fix sizing when maximized
    
    The ListBox was expanding when maximized on large screen sizes. It appears
    that the EggColumnLayout can deal with this just fine by doing halign to
    GTK_ALIGN_START since it will try for an optimal preferred size of
    something rectangular.
