Recent update-ca-certificates may output on stderr, even when the command succeeds. This causes autopkgtest to consider a test run failed.
The long-term fix will hopefully happen in openssl, in the mean time we can work around the issue. Ignoring stderr should be safe: if update-ca-certificates in the testsuite would not work correctly, the certificates will not be installed and the test will fail safely.
