    flatpak: add --share=network
    
    This allows network access for building so that things like autogen.sh
    can do "git submodule init" which is a common practice. Since we can't
    rely on flatpak-builder to do this for the topmost project, we need this.
    
    However, in the future, it would be nice to detect if it is necessary and
    only --share=network for the appropriate phase.
