[libvirt] [PATCH] Fix TLS tests with gnutls 3

[Daniel P. Berrange]

From: "Daniel P. Berrange" <berrange at redhat.com>

When given a CA cert with basic constraints to set non-critical,
and key usage of 'key signing', this should be rejected. Version
of GNUTLS < 3 do not rejecte it though, so we never noticed the
test case was broken
