Update readiness/liveness probes

Updated to reflect general recommendations from the rabbitmq docker repository (and via docker-library/rabbitmq#174 (comment)), and to generally support non-alpine versions of the image as the ubuntu image does not include wget (or curl) whereas `rabbitmqctl status` is included in both images, additionally the check looks more into the service status rather than the management plugins status.
