Subject: [PATCH] HADOOP-18487. change scope so that protobuf explicitly
 exported again

...lets see if that helps things to build, though it does look like a
mvn repo change.

key point: dependencies are the same as before, but protobuf can be excluded
by downstream projects and all RPC code will still work.
