RFR: 6606767: resexhausted00[34] fail assert(!thread->owns_locks(), "must release all locks when leaving VM")

[Alex Menkov]

Please review the fix for JDK-6606767.
The original issue is not reproducible.
The fix:
- resexhausted003 and resexhausted004 are un-problemlisted
- resexhausted004 is problemlisted on linux due JDK-8253916 (resexhausted004 executes
  resexhausted001/resexhausted002/resexhausted003 randomly, and resexhausted001 fails on linux)
- resexhausted003 is updated to throw SkippedException if OOME is not thrown;
- resexhausted004 is updated to catch SkippedException from resexhausted001..003, also logic is slightly simplified
