[Rd] minor problem in XML package

[William Dunlap]

[The package XML is labelled ORPHANED and a comment says the CRAN team
maintains it.  I am not sure what address to send this to.]

In package XML version 3.98.1.11, RUtils.c registers the C function
RS_XML_xmlNodeChildrenReferences twice.  The registration information is
identical but this could cause maintenance problems if the routine were
changed.

% grep -n RS_XML_xmlNodeChildrenReferences RUtils.c
205:        ENTRY(RS_XML_xmlNodeChildrenReferences, 3),
231:    ENTRY(RS_XML_xmlNodeChildrenReferences, 3),

One of them should be deleted.
