Low: libcommon: Ignore CDATA of metadata of the resource.

When CDATA is included in metada of the resource, an error occurs.

Oct 9 09:35:57 rh66-tomcat1 crmd[11182]: error: crm_abort:
pcmkRegisterNode: Triggered assert at xml.c:595 : node->type ==

XML_ELEMENT_NODE

The present conditions are only resources of tomcat, but, in
consideration of the future, should ignore CDATA.
