Move gitlab-shell checkout to top level of GDK
What does this Merge Request do?
This solves the same problem as !1081 (merged), but for gitlab-shell.
We have a funny solution with a symlink to handle GOPATH in gitlab-shell. We don't need GOPATH anymore so we can get rid of the symlink. This is better for developer ergonomics.
