Indeed piuparts does remove init-system-helpers before
shibboleth-sp2-utils. I hadn't noticed before but it's in the log:

Why would puiparts do it in this order? shibboleth-sp2-utils depends on
init-system-helpers!

The version comes from debhelper's changelog in jessie-backports [1].
It's when dh-systemd was moved to debhelper.

Since adding this version constraint was motivated by piuparts's report,
it may not be necessary in the end...
