fix: failing to clone from gopkg

you need to execute this after pulling a cloned repo
  git submodule sync --recursive

This should fix this issue:
	Cannot obtain refs from GitHub: cannot talk to GitHub: Get https://github.com/go-yaml/yaml.git/info/refs?service=git-upload-pack: net/http: request canceled (Client.Timeout exceeded while awaiting headers)

It looks like it is a known issue: niemeyer/gopkg#63

So we are going around gopkg and cloneing from github directly.
