Unit tests fail with go 1.10

[mklimuk]

Go 1.10 brings some refactoring in archive/tar package. It causes several rocker unit tests to fail. Apparently it comes from this fragment of build/copy.go (line 141):

if _, err = io.Copy(ioutil.Discard, tarSum); err != nil { return s, err }

The problem occurs in tar writer's Close()/Flush() method. Not sure how to tackle it though. If I ignore the error everything works fine but it is not an acceptable solution of course.

Closing this issue as we are not able to address it. Sorry.
