Subject: [PATCH] test: wait for interface to come online before checking DNS
 scopes

The current test is flaky because it creates a new interface definition,
calls networkctl reload, and then calls resolvectl show-cache. If
resolved has not received the changes and setup the DNS scopes for the
interface, show-cache will be empty for that interface.

Part 2 of #39602
