[glib-networking/mcatanzaro/rerun-tests] Run GnuTLS connection tests with TLS 1.3 disabled

[Michael Catanzaro <mcatanzaro src gnome org>]

commit 9619f0ee40d2634fdb17dc0deef8c758be0fc065

    Run GnuTLS connection tests with TLS 1.3 disabled
    
    Some tests have regressed with TLS 1.2, but I didn't notice because we
    are currently not testing it anywhere. Run all the tests with TLS 1.2
    as well as TLS 1.3.
    
    This is currently expected to fail due to #84 and #88.
