Update haskell-hlint checker to HLint-3.0

[jdnavarro]

HLint v3.0 has been recently released.

• Now .hlint.yaml is the default configuration file. (I think this was already supported in the latest releases of 2.0).
• When there is a suggestion or warning it returns a 1 exit code by default. We have to pass --no-exit-code to avoid it.

The source location always includes the end of the column now. I removed the optionals in :error-patterns, and it works as expected, but couldn't figure out how to update the tests.

In any case, it still works when leaving the optional end of the column.
