init-ifupdown: Attempt to make our init script available for everyone

Create the /run/network directory for all of our systems. The
proper way with tmpfiles.d ends with a depedency mess that has
no point in being debugged.

My local build hasn't completed yet but we need to rush. Let the
CI test this change and we will see.
