[Oilpan] Change a test behavior

Change the behavior of HeapTest.TraceDeepEagerly.

Before this change, this test fails if GC uses a large stack memory to recursive trace.
This CL
1) makes recursive tracing deeper, to ensure lazy tracing occurs.
2) avoids recursive trace if lazy trace has been called, to finish tests quickly.
