build: turn :block-node-protobuf-pbj into an alternative to :hapi

Using the same Module Name and Gradle capabilities, the Modules are
then interchangeable. If both are on the Module Path, because :hapi
is referenced transitively, Gradle will resolve the conflict by
picking :block-node-protobuf-pbj only.
