    build: Fix vala build with gstapp in non-standard location
    
    Some of the headers include `<gst/app/gstappsink.h>`, which is part of gstreamer-app-1.0,
    the pkg-config file only lists gstreamer-1.0 as a dependency, though. It is not guaranteed
    that they share the installation paths and indeed it is not the case on NixOS, resulting
    in build failure.
    
    Let's properly declare our dependencies so that vala-gen-introspect can find them.
