Bug#335665: kudzu patch to not use PCI_FILL_CLASS

PCI_FILL_CLASS is a RH specific patch to pciutils that upstream isn't
interested in.  This patch removes uses of that feature from kudzu which
allows current CVS to compile on a system without RH patches to pciutils.

By the way, the main kudzu page at http://rhlinux.redhat.com/kudzu/
has two broken links on it; the "rawhide" link and the "cvsweb" link.
