Our utils/docker-run wrapper is needed to provide a reproducible build
environment: tools, variables, etc... but is not meant for isolation. As
such, we do not care what the network configuration is used.

In some settings (e.g. enterprise networks), it is often the case that a
VPN is in use, especially in those wonderful times of widespread remote
work.

Letting Docker decide on the network setup, will most usually lead to it
creating a private network that is NATed onto the principal network
interface, leading to non-functional network in the container when a VPN
is in use.

As such, always use the host network configuration, and do not let
Docker create a private network for the container.
