Disable "missing-kind-signatures" warning

This is a new warning in GHC, it wants us to write
```
type ToPairs :: * -> Constraint
```
in addition to
```
class ToPairs t where
```

I am not sure it's a good idea to require it everywhere, so for
now I just disable this warning to let the existing code compile
without warnings.
