adding gogo proto descriptor to deps of gogo proto compiler

[linzhp]

Some of the proto-generated code depends on "github.com/gogo/protobuf/protoc-gen-gogo/descriptor", leading to the follow error a build time. This PR fixes it.

Check that imports in Go sources match importpath attributes in deps.

I believe this fixes #1385
