Simplify kube-rbac-proxy startup script

[juanluisvaladas]

CNO tries to create the objects defined in bindata's files in
lexicographic order, so we can rely on the secret being created when
this starts.

I don't know what happens if during an upgrade the CNO
fails to create the services, so it's probably a good idea not to
backport this to 4.6.

AIUI, the Secret isn't created by the CNO, it's created by the service-cert controller. So we can't actually rely on it existing.

If you wanted to create an empty secret, that might work. I believe the mount would be automatically updated when the serving certs are created.

@squeed We wait for the cert to be mounted later:

cluster-network-operator/bindata/network/openshift-sdn/sdn.yaml

Lines 209 to 212 in cea0ebf

	while [[ ! -f "${TLS_PK}" || ! -f "${TLS_CERT}" ]] ; do
	log_missing_certs
	sleep 5
	done

Oh duh.
