Fix transitive dependencies for netty-handler

Exclude netty-codec-protobuf and netty-codec-marshalling.
We don't want to depend on those jars, because they depend on protobuf/marshalling jars we do not need.
And then JPMS applications may fail to start with FindException because, for example, JBoss Marshalling is missing.
