lint-staged: Duplicated errors

@okonet thank you for the package.

I got duplicates in output while trying to use link-staged with husky, here’s my config:

 "scripts": {
    "precommit": "lint-staged"
  },
  "lint-staged": {
    "gitDir": "../../",
    "linters": {
      "app/front-end/src/**/*.{js,jsx}": "eslint --quiet"
    }
  },

Output:

> husky - npm run -s precommit

Looks like lint-staged and husky both output the same error. Here I got 2 errors from lint-staged and one from husky.

Can we add some --silent option for lint-staged? So it would not output the errors, but throw them forward to husky (I also use husky for another lintings).
