pytest: disable broken test

Seems like it's using an old version of pyln-client, which had the bug
of referring to long_desc:

```
def test_local_dir_install(node_factory):
        """Test search and install from local directory source."""
        n = get_reckless_node(node_factory)
        n.start()
        r = reckless([f"--network={NETWORK}", "-v", "source", "add",
                      "tests/data/recklessrepo/lightningd/testplugpass"],
                     dir=n.lightning_dir)
        assert r.returncode == 0
        r = reckless([f"--network={NETWORK}", "-v", "install", "testplugpass"], dir=n.lightning_dir)
        assert r.returncode == 0
>       assert 'testplugpass enabled' in r.stdout
