    I hate libcanberra!
    
    It's the only library where the pkg-config name doesn't match the vapi,
    and meson does NOT like this.
    
    This commit allows us to build without requiring and linking to
    libcanberra-gtk (the GTK 2 version).
    
    The proper solution is to stop using libcanberra and use gsound instead.
