util: Don't ignore non-running interfaces

We want to be able to configure interfaces which are not running. Just
because we don't have a cable plugged into the machine doesn't mean we
don't want to have the option to configure it from the host

Tested:
    Built an image and made sure the interface was now present and
    configurable even if it had no link present.
