    flatpak: Pin libportal dependency to release 0.4
    
    We would need to update the dependency for changes in the build process,
    however also the API is currently changing. Upstream has already
    suggested in another case (epiphany!1027) to stay on a tagged release
    until a new stable release is available. Let's do the same for eog.
