[java] use own Netty version for kudu-subprocess

It turned out that transitive dependencies of the kudu-subprocess
package brought its own version of various io.netty modules into the
package as a shaded dependency.  Particularly, the dependency chain was:

  org.apache.kudu:kudu-subprocess
    org.apache.ranger:ranger-plugins-common
      org.apache.ranger:ranger-plugins-audit
        org.apache.hadoop:hadoop-common
          org.apache.hadoop:hadoop-auth
            org.apache.zookeeper:zookeeper
              io.netty:netty-handler

This patch addresses the issue.
