 Go 1.11 is adding preliminary support for Go modules, replacing the
 GOPATH-based approach.

 obfs4 is adding `go.mod` and `go.sum` files, which use the Go modules
 support to fetch the dependencies. We disable that in #28310 as the go
 libraries we build are not currently recognized as Go modules.

 We should change how we build our Go libraries so that they can be used as
 Go modules.
