golint zero exit code

[insidieux]

Describe the bug

lint-golint stage in Makefile does not return error code on non empty warnings after processing.

To Reproduce

1. Remove comment from one of exported type in source code
2. make lint-golint

Expected behavior

As the result make must fail and return non zero exit code.

make[1]: *** [lint-golint] Error 1
make: *** [lint] Error 2

Environment:

• Version: v1.0.0
• GOOS: darwin, linux

Additional context

In golint documentation there is a flag --set_exit_status, which must solve problem.
