Unable to use "go vet" when using "dep ensure"

[delanne]

When I do "dep ensure -v" in order to fech dependencies, the "go vet" command fails with:

vet: /go/src/foo/bar/main.go:4:2: could not import github.com/Sirupsen/logrus (can't find import: foo/vendor/github.com/Sirupsen/logrus)

In order to be able to use the "go vet" command, I need to do a "go get" after "dep ensure"

In attachment: dep_issue.zip in order to reproduce the issue.

$ unzip dep_issue.zip && cd dep_issue && docker run --rm -v "$PWD":/go -w /go golang:1.8.0 ./build.sh

Seems to be a vet bug instead of a dep issue (golang/go#17571)
