Fix double packaging of commons-io

Id12780948 added transitive dependency to commons-io. This is wrong
as commons-io is already provided by the Gerrit itself and therefore
is contained in gerrit.war archive. But with the change above it's
contained twice: in gerrit.war and in replication's JAR.  Change
commons-io to be included as non-transitive dependency.
