Fix ginkgo compilation error
Fix ginkgo compilation error

Ginkgo 1.9 adds a new dependency to `hpcloud/tail`. This dependency was not copied which led to a compilation error for ginkgo.
This only happened when the ginkgo bin was not on `$PATH` and had to be compiled manually.

This commit fixes the issue by copying _all_ dependencies to the current directory.
