Subject: Do not fail when writing root password and /etc/shadow is missing

Do not fail when writing root password and /etc/shadow is missing

I had this failure when testing https://github.com/systemd/mkosi/pull/1442. But
it would happen whenever the installed system has no /etc/shadow and we want to
set the password, so it's worth fixing regardless.
