ci: cdrouter: flush DNS relay cache on loopback instance as well

Browse Source 
Since the unbound upstep from 1.22 to 1.24.1 (commit d453d848c0), DNS
resolution now also uses a loopback unbound instance. The existing DUT
init script only flushed the "lan" DNS relay cache, causing stale
negative DNS entries on the "lo" instance to persist. This led to USP
agent (obuspa) STOMP connection failures during CDRouter-Wireless tests,
as controller.cdroutertest.com could not be resolved.

Flush the "lo" DNS relay cache before "lan" to ensure both instances
have clean state before CDRouter tests start.
