[jdk11u-dev] RFR: 8246114: java/net/MulticastSocket/Promiscuous.java fails after 8241072 (multi-homed systems)

[Jonathan Dowland]

This is a test-only backport. This test fix was merged in 11.0.13-oracle.

The test started to fail in JDK mainline after JDK-8241072, but that change is not in-scope for jdk11u. The test in jdk11u right now passes (for me) before and after applying. The test fix seems reasonable to me despite the failure not triggering in 11u (yet?)
