Update etcd path test to always use kindWhiteList

Most types now have valid rest mappings because
NewDefaultRESTMapperFromScheme no longer ignores certain import
paths.  Thus we can no longer use the lack of a valid REST mapping
as an indicator for when to use kindWhiteList.  Thus kindWhiteList
now serves as a whitelist for all kinds and not just those that
formally had no mapping.  This does mean that we could whitelist
kinds due to a name conflict, but that is unlikely as names such as
GetOptions are not appropriate for new objects.
