TT#26264 Remove maintainer script directly calling init scripts

We are in the process of removing the obsolete init scripts, so trying
to use them directly will make these operations not work at all.

In addition these actions are always denied on NGCP via our permanent
policy-rc.d, so there is no point in even trying.
