Update CodeClimate settings

https://codeclimate.com/github/saltstack/salt/pull/51461 had a matching
block with mass of 38. Apparently that's too low because that code was
not even the same at all. Bumping it up a bit to avoid false positives.

Also disable argument count checks because we really don't need that
here.
