    flatpak: Build with meson
    
    Meson is a fast-moving project, and while we don't require the very
    latest version, the requirement is still recent enough to not
    assume its general availability. However when building the flatpak,
    we can easily ensure a recent enough version by bundling, so switch
    the manifest to meson builds.
