cilium: Make policy wait to wait for ready state.

cilium policy wait is used in tests to wait for all the endpoints to
have the given policy version. The intent is to be able to test that
policy right after, which is really possible only after all the
endpoints have also finished recomputing the new policy and
regenerated corresponding bpf.

This patch changes "cilium policy wait" to also wait for all the
endpoints to be in the "ready" state to facilitate the intended use
and make tests more deterministic, or "less flaky".
