doc: ref 9/ceph-mon using relative path

sphinx complains when it failed to find the referenced file using the
absolute path whose root is the $(top_srcdir)/doc/man when rendering
man pages. but it is able to find it when rendering the html, because
build-doc specifies $(top_srcdir)/doc/ as the source directory.
