Until https://github.com/coreos/clair/pull/193 is merged, having
vulnerabilities that are tagged both rhel and centos would duplicate in
the database or use a change that requires a migration.
But presently due to the fetcher logic, the rhel provided
vulnerabilities are labelled for centos, and then the namespace does not
match and therefore not tested against.
So until such a day that a vulnerability could have both rhel and centos
label, then hack this in. It'll accomplish the same during this interim.
