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