[master 4/4] livemedia-creator: Raise an error if url is used without networking

[dashea]

From: Fabian Deutsch

Because livemedia-creator is using a media based installation by default,
no networking is brought up automatically. If then the url installation
method is used, it fails with an unclear reason.

This patch adds a check to raise a clear error if the url installation
method is used insisde the kickstart but no networking is configured.
