merged yannk's patch for RPC::XML::LibXML

https://github.com/tokuhirom/p5-RPC-XML-Parser-LibXML/pull/1

• Specify sane default parser options (disallowing external entities)
• Bump LibXML to 1.70 (because we need to specify %param to new() and LibXML changed that method signature in a recent version)

I recommend to latest version if you are using it.
