JVM BE: Ignore a recently introduced test for JVM ABI K1/K2 comparison

The test depends on
LanguageFeature.EqualityConstraintForOperatorsUnderAssignments (from 2.3)
which effectively is seen as disabled for
the K2 pipeline because `supportsFeature` is still delegated to the
language settings from the K1 pipeline
(see delegated anonymous object at org.jetbrains.kotlin.test.TestSetupUtilsKt.runWithEnablingFirUseOption)
