 I guess the configure script will prefer one over the other if both are available.

 If the configure script prefers iptables over nftables, then the proposed patch
looks good to me. If, however, the configure script prefers nftables over
iptables, then the patch is wrong because the keepalived would be built
differently depending on whether nftables is built first or not.
