ec2_utils: fix MetadataLeafDecoder that returned bytes on empty
the MetadataLeafDecoder would return a bytes value b'' instead of an empty string if the value of a key was empty. In all other cases the value would be a string. This was discovered when trying to json.dumps(get_instance_metadata()) on a recent OpenStack, where the value of 'public-ipv4' was empty. The attempt to dump that with json would raise TypeError: b'' is not JSON serializable
