Add tests for distroless image
Follow up on https://github.com/kubernetes-sigs/iptables-wrappers/pull/6
In order to run the tests in a distroless image, I rewrote them in Go so we can compile them to a static binary and just copy to the image. They work pretty much like the bash version. In addition they also check that the ip6tables binary resolves correctly. I also added a couple of tests for rules added for ip6.
The distroless image is pretty much a copy of what's used in https://github.com/kubernetes/release/blob/master/images/build/distroless-iptables/distroless, but with a few tweaks to drop the extra dependencies like dash. We could maybe simplify it if we didn't use the installer script.
