[libvirt] [PATCH] Fix import of private key with older gnutls

[Daniel P. Berrange]

With older GNUTLS the gnutls_x509_privkey_import function is
unable to import our private key. Instead we must use the
alternative gnutls_x509_privkey_import_pkcs8() (as certtool
does).

* virnettlscontexttest.c: Fix import of private key with
  older gnutls. Also add missing newlines to key
