JDK 9 RFR of 8150206: Demote LFMultiThreadCachingTest.java to tier 2 until resolution of JDK-8150014

[Martin Buchholz]

It's easy enough to get the test to pass by delambdafication.

But we may not want to fix the test because it's not clear whether
it's a jdk lambda bug or not, and we don't sweep bugs under the rug.

Maybe instead of a "tier2" bucket we really want a "test found a bug
that's not yet fixed" bucket?
