> USN-9001-2: ca-certificates update

USN-9001-1 fixed a vulnerability in ca-certificates, ca-certificates-java. This update provides the corresponding fix for Ubuntu 18.04 LTS and Ubuntu 20.04 LTS. Original advisory details: It was discovered that the ca-certificates JKS integration was not working properly, resulting in CA certificates removed from the system bundle not being removed from the JKS keystore. This update corrects the feature and resyncs the keystore with the system CA certificates list.
