RFR: 8260466: Test TestHeapDumpOnOutOfMemoryError.java needs multiple @test sections

[Harold Seigel]

Please review this change to fix JDK-8260466.  The fix adds separate @test sections for the two tests in TestHeapDumpOnOutOfMemorty.java.  The change was tested by using Mach5 to run the test on Linux, Mac OS, and Windows.

Thanks, Harold
