[bug#54335] [PATCH v3 08/10] gnu: Add go-google-golang-org-protobuf.

[Dominic Martinez]

* gnu/packages/golang.scm (go-google-golang-org-protobuf): New variable.
---

I took this go-google-golang-org-protobuf definition from #54560. I had
disabled builds/tests before because this package has many subpackages and no
top-level files, which the go-build-system doesn't directly support, so this
modifications builds and tests all the subpackages.
