Make golint run on nested packages

[rdsubhas]

This is a good starter issue.

Presently we run golint on only main package .. We'd like to run it nested packages, such as go run github.com/golang/lint/golint ./.... The only problem is, one file bindata.go is generated using go-resources and hence it has one linting issue in it, which we can't auto-fix since its an auto-generated file. Find a way to run golint recursive while either ignoring this file, or automatically fixing the lint error.

End result: we'd like to run golint on all packages ./...
