[libvirt] [PATCH] tests: detect gnutls errors

[Eric Blake]

* tests/virnettlscontexttest.c (testTLSLoadKey): Report errors.
---

Something in gnutls 2.8.5 (RHEL 6) was more leniant than gnutls
2.8.6 (Fedora 14).  This still doesn't solve the failure, but at
least gets us to see that newer gnutls_x509_privkey_import doesn't
like our define of PRIVATE_KEY.
