Do not allow setting auth, access or chpass providers for LOCAL

The LOCAL provider does not have a mechanism to load alternate
auth, access or chpass backends, nor does it make sense to do so.

This will throw a configuration error if these values are
specified (unless they are explicitly also set to 'local')
