Fix run parts missing operand

[hidrarga]

Problem

OpenVPN is sending arguments when running the down script. The problem is that run-parts can't handle these extra arguments, and then crashes…

Solution

I don't have a really clean solution, except creating a bash script that execute run-parts without these extra arguments

Thanks!

Btw I'm thinking it would be nice to document this new run-script mechanism in doc/ADMIN.md if you have the energy for it 👍

That's a good idea, I'll do that in another PR though :)
