Add iptables testing framework.

It would be preferrable to test iptables via syscall tests, but there are some
problems with that approach:

* We're limited to loopback-only, as syscall tests involve only a single
  container. Other link interfaces (e.g. fdbased) should be tested.
* We'd have to shell out to call iptables anyways, as the iptables syscall
  interface itself is too large and complex to work with alone.
* Running the Linux/native version of the syscall test will require root, which
  is a pain to configure, is inherently unsafe, and could leave host iptables
  misconfigured.

Using the go_test target allows there to be no new test runner.
