virsh.pod had several instances in which it referred to "the
documentation" which was a little puzzling to me since it is
documentation. Reading the document from end to end makes it clear
that it means a specific URI which was noted previously in the text,
but I had never noticed those URIs in several years of referring to
the man page. This patch adds those URIs to several additional places
in the text.
