Now that docbook-xml and docbook-xsl use the xmlcatalog class, xmlto can stop
shipping a hand-coded catalogue.
It still needs to keep the wrapper so that the sysroot catalog is used instead
of /etc/xml/catalog. The wrapper is native-specific so mark it as such.
Note that this does effectively break xmlto on the target as the xmlcatalog
class doesn't write a catalog for the target yet, but I'm hoping that nobody
actually uses it on target.
