Bug#767951: systemd-cron: "crontab -r user" will remove root crontab

[Alexandre Detiste]

Package: systemd-cron
Version: 1.3.4-1
Severity: important

Dear Maintainer,

I've discovered that deluser from the adduser package will call crontab
with unexpected parameters [1, L351], that doesn't match the one documented
in vixie's crontab manpage [2].

As a result, "crontab -r someuser" will instead allways remove root's crontab
(/var/spool/cron/crontabs/root)

As the behaviour expected by adduser/deluser might be expected elsewhere,
this has to be fixed in systemd-cron's crontab.
