[gnome-software/wip/kalev/umask-022] Enforce a more permissive umask

    Enforce a more permissive umask
    
    Override the umask to 022 to make it possible to share files between the
    gnome-software process and flatpak system helper process. Ideally this
    should be set when needed in the flatpak plugin, but umask is
    thread-unsafe so there is really no local way to fix this.
    
    This matches flatpak PR https://github.com/flatpak/flatpak/pull/2856
