libxml-native by default uses a XML catalogue at /etc/xml/catalog, instead of
the one in the sysroot. Until this is fixed (#13260) override the XML catalogue
manually in the recipe to point explicitly at the docbook-xml and docbook-xsl
catalogues.
This fixes either complete build failures (where the host doesn't have
docbook-xml installed) or slow builds (where the host doesn't have docbook-xsl
installed).
