Bug#791944: /etc/init.d/sendsigs kills systemd-udevd upon shutdown, causing dmsetup to hang

[Pali Rohár]

Problem is still present in Stretch and cause system hangs at
shutdown/reboot when using LUKS encryption. See:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=792552#153

Stretch has only version 232. As in Jessie is version 215 and according
to first post this problem was introduced in 221, it is a regression
when upgrading from Jessie to Stretch.

Please fix this problem in Stretch.
