I can reproduce this locally with autopkgtest, like this:
I can also reproduce it with a vanilla Debian unstable debvm:
$ debvm-create
...
$ devm-run
...
root@testvm:~# apt install --reinstall systemd
...
Setting up systemd (262~rc2-1) ...
Can't exec "kill": No such file or directory at
/usr/bin/deb-systemd-invoke line 179.
Thanks! cheers, josch
