libxml-libxml-perl: add recipe

This module is an interface to libxml2, providing XML and HTML parsers \
with DOM, SAX and XMLReader interfaces, a large subset of DOM Layer 3 \
interface and a XML::XPath-like interface to XPath API of libxml2. \
The module is split into several packages which are not described in this \
section; unless stated otherwise, you only need to use XML::LibXML; in \
your programs.
