Remove the noconfig flag

Summary:
D11196 introduced a regression that made it impossible for coffeelint to read any configuration. I'm reverting the change in that diff.

Created a pull request changing the documentation of coffeelint to make sure I'm interpreting this flag correctly: https://github.com/clutchski/coffeelint/pull/364

Test Plan:
- patch
- npm install -g coffeelint

- create a `test.coffee` file with:
```
# 1234567890
```
- `arc lint test.coffee`
```
 OKAY  No lint warnings.
```
- create a `coffeelint.json` with
```
{
  "max_line_length": {
    "value": 10
  }
}
```
- `arc lint test.coffee`, expected output:
```
>>> Lint for test.coffee:

   Error  (COFFEE)
    Line exceeds maximum allowed length.

    >>>        1 # 1234567890
```
- create a `.arclint` with
```
{
  "linters": {
    "coffeelint": {
      "type": "coffeelint",
      "coffeelint.config": "coffee_lint_config_with_different_name.json"
    }
  }
}
```
- rename `coffeelint.json` to `coffee_lint_config_with_different_name.json`
- `arc lint test.coffee`, expected output:
```
>>> Lint for test.coffee:

   Error  (COFFEE)
    Line exceeds maximum allowed length.

    >>>        1 # 1234567890
```
