Remove malicious import-package from config-model-fat.
config-model-api does not seem to leak InnerCNode anymore.
<!-- TODO: The fat bundle becomes more brittle for each package added below. Use interfaces in model-api instead. -->
com.yahoo.vespa.config,
com.yahoo.vespa.config.buildergen,
- com.yahoo.config.codegen <!-- TODO remove when InnerCNode is no longer exposed by model-api -->
</Import-Package>
</instructions>
</configuration>
