    flatpak: Switch to Meson
    
    The Autotools build didn't use --disable-dogtail, even though the SDK
    doesn't have Dogtail. It only worked because configure.ac doesn't
    actually check for the presence of Dogtail. The Meson build doesn't
    check for it either, but merely to imitate the Autotools build.
    
    It's better to spell out exactly what's going on.
