debvm-create: avoid using passwd --delete
passwd will chroot() into the target tree and then load shared
libraries. This tends to work badly for old releases and for foreign
architectures or combinations thereof. As a result, it sometimes fails
with
Cannot determine your user name.
In practice, it removes a single asterisk from the first line of
/etc/shadow (at least for jessie to trixie). This is something, we can
also do via sed.
