net-test: upgrade to iptables 1.8.4-3

and various other changes to make things actually build

One of the more interesting aspects of things is that
the root directory must be root:root 0755 or systemd
fails to install.

Tested: built via ./build_all_rootfs.sh
  net_test.rootfs.amd64.bullseye.20200417
  net_test.rootfs.arm64.bullseye.20200417
  net_test.rootfs.armhf.bullseye.20200417
  net_test.rootfs.i386.bullseye.20200417

  Haven't tested they work, but this is what is needed
  to even make them build.
