[PATCH] iptables: use autoconf to process .in man pages

[Andy Spencer <andy753421@gmail.com>]

This fixes a bug in iptables.8 and ip6tables.8 where @PACKAGE_VERSION@
was not processed in the VERSION section. It also simplifies the
Makefile by avoiding some sed commands.

Yea, I don't know how I feel about having a .in.in, but it seems to work
well enough.
