[libvirt] [PATCH rust 1/5] fix bug integration test with rust multithreading

[Sahid Orentino Ferdjaoui]

The open_auth test cases were randomly failling. It seems that because
tests are executed in parallel if a sasl connection is open when an
other happen in same time from the same libvirt connection an error
happens: "Failed to start SASL negotiation: -4 (SASL(-4): no mechanism
available: No worthy mechs found)".
