In LightAnalysisModeTestGenerated skip tests ignored in JVM

When a test is marked as ignored in JVM BE (i.e. IGNORE_BACKEND: JVM)
it's ignored in LightAnalysisModeTestGenerated. This means that
this tests is expected to fail. However, often tests that fail
in JVM blackbox tests, don't fail in LAMTG, therefore it's reasonable
to skip these tests in LAMTG at all.
