While here, USE_GROFF is not needed, change _rbldns user homedir from
/var/empty to /nonexistent and we can still use -r /var/empty for the

rbldnsd is a small and fast DNS daemon which is especially made to serve
DNSBL zones. This daemon was inspired by Dan J. Bernstein's rbldns
program found in the djbdns package.
