Go doesn't like symlinks like this in it's GOPATH

Lots of Go's tools won't traverse a gopath that contains symlinks: https://github.com/tools/godep/issues/71

The suggested approach is to use a reverse symlink, so have the gopath directory the actual directory and have the checkout dir a symbolic link.

Inspect the repository's Go and Buildkite pipeline setup to find where GOPATH and checkout paths are configured. Compare the current symlink arrangement with the reverse-symlink approach described in the issue, then verify that the Go tools and pipeline can operate successfully.
