Subject: Honor ENTRYPOINT in image

When an image has an ENTRYPOINT defined, we should be honoring it. The
problem is described in issue #321.

Also, added buildah binary to test runtimes for testing entrypoint and
will also allow us to test podman build as well.

Signed-off-by: baude <bbaude@redhat.com>

Closes: #322
