[gnome-builder] build: change auto to no if we fail to locate flatpak and deps

[Christian Hergert <chergert src gnome org>]

    build: change auto to no if we fail to locate flatpak and deps
    
    We might not have located libgit2-glib+flatpak, so ensure that we set
    auto to no so that people building the software know that we failed to
    set proper dependencies.
