Add new e2e-test container to export ipcs from util-linux

This container will be used to exercise the HostIPC functionality in
e2e-node tests.

The version of `ipcs` shipped in busybox performs operations that get
blocked by SELinux on hosts where it is enabled. The version of `ipcs`
in util-linux does not perform those operations, rather it checks
whether the /proc files it needs are available and proceeds to reading
from them directly.

Using `ipcs` from util-linux makes these tests pass, even when running
under SELinux enabled, so let's use them here.

Tested: On a host where Docker with SELinux enabled:

- Checked that `ipcs` from busybox does not work:

  $ docker run busybox ipcs -m
  kernel not configured for shared memory

- Checked that the one from this container does work:

  $ docker run gcr.io/kubernetes-e2e-test-images/ipc-utils-amd64:1.0 ipcs -m
