    Demos: Fix Demo Data Path on Windows
    
    The relocatable data path for the gtkmm demos was still set in the
    gtkmm-2.x days.  Update the path so that gtkmm-2.x and gtkmm-3.x can be
    really parallel-installed on Windows in the same root path.
    
        * demos/gtk-demo/demo-common.cc: Update the relocatable demo data
          path for Windows so that we don't have to fight for the same
          space with gtkmm-2.x.
