Upgrade the java and tc server buildpacks directly

- The java and tc server buildpacks work with both cflinuxfs2 and cflinuxfs3. We have to upgrade them directly instead of using stage and promote phases because there is no way to stage them with stack association. We assume that older versions of these buildpacks already exist on the foundation and that they are stack associated when we perform an upgrade.
