Support domain users with no valid password, for receive-only MTAs

Some use cases, like receive-only MTAs, need domain users for receiving emails, but have no real need for passwords since they will never use submission.

Today, that is not supported, and those use-cases require the administrator to come up with a password unnecessarily, adding complexity and possibly risk.

chasquid's userdb could be extended to support users that don't have a valid password, thus exist for the purposes of delivering mail, but always fail authentication. chasquid-util user-add would also need extending accordingly.

Thanks to xavierg who suggested this feature on IRC.
