Add configuration option to allow sddm.login to be called when the password is blank.
This is useful when another PAM module (for example, a security key is present) is sufficient for authenticating the user.
Made it a configuration option instead of default behaviour as I believe submitting an accidental blank password is a lot more likely than a user wanting to intentionally submit a blank password, so it's fine if the latter has to change a default first to allow their use case.
