test(java-oracle): DnsRun records DNS as Java FILIUS runs it

Browse Source 
A resolver's lookup on the new dns-lan network (A, MX, a referral by NS,
an unknown name, a missing server): every frame and the call's result.
ScenarioNetwork installs a scenario's DNS servers. The Swift comparison
reads only scenarios with a Swift result.

Measured: Java's text messages (ID=... QR=... header, question and record
lines), no question in the answer, RCODE 0 always, a referral in the answer
section, an iterative resolver waiting 5 RTT per query.
