Reproduction steps:

1. Run GO111MODULE=off go get -u github.com/myitcv/gobin
2. Run go generate in the same directory as myinterface.go
3. Observe the following error:

$ go generate
failed to run /Users/joe/projects/veesixissue/.gobincache/github.com/maxbrunsfeld/counterfeiter/v6/@v/v6.0.2/github.com/maxbrunsfeld/counterfeiter/v6/v6: fork/exec /Users/joe/projects/veesixissue/.gobincache/github.com/maxbrunsfeld/counterfeiter/v6/@v/v6.0.2/github.com/maxbrunsfeld/counterfeiter/v6/v6: no such file or directory
myinterface.go:3: running "gobin": exit status 1

I have tried changing the go generate directive in myinterface.go to be:

//go:generate gobin -m -run github.com/maxbrunsfeld/counterfeiter . MySpecialInterface`

This works, but it causes an extraneous dependency to be registered in go.mod:

github.com/maxbrunsfeld/counterfeiter v0.0.0-20190111051351-d7285d544cff // indirect
github.com/maxbrunsfeld/counterfeiter/v6 v6.0.2

This makes me believe that either gobin is failing to correctly use the tagged v6.0.2 dependency, or I've messed something up when releasing the v6.0.2 counterfeiter dependency. Which is it?
