    Make ninja a virtual sysdep
    
    This ensures it will be installed by 'jhbuild sysdeps --install' so that
    users get a sane error message if it's not installed, before trying to
    build modules. We were never able to do this in the past because
    /usr/bin/ninja was some IRC client on Fedora, but that's not the case
    anymore.
