Fix crash with old libxml2

Certain libxml2 versions (such as the 2.7.6 commonly seen in older
distributions, but apparently only on x86_64) contain a bug that causes
xmlCopyNode, when called on a XML_DOCUMENT_NODE, to return a node that
xmlFreeNode crashes on.  Arrange to call xmlFreeDoc instead of
xmlFreeNode for those nodes.
