fix deletion of root password againmain

Unless passwd is installed, shadow is not enabled. That is, shadow being
enabled is not a boolean. It can be enabled per user and systemd enables
it for its own users, so shadow exists, but may not contain the root
user. Thus the password deletion logic need a bit more fancyness for
covering systems that lack the passwd package.
