Bug#827376: init-system-helpers: invoke-rc.d unconditionally uses /sbin/runlevel without depending on a package providing it

invoke-rc.d is actually behaving correctly already, it just shows that
confusing error message (which is now fixed in git, see my other
reply).

Eek, no. The "runlevel" concept only exists in SysV init. upstart and
systemd try to emulate it to some degree, but only approximately as
they are built on completely different concepts. I actually worked on
making invoke-rc.d not require the concept of runlevel at all under
systemd (I believe 1.35 is good in that regard now).
