RFR 8234058: runtime/CompressedOops/CompressedClassPointers.java fails with 'Narrow klass base: 0x0000000000000000' missing from stdout/stderr

[Harold Seigel]

Hi,

Please review this trivial change to stop running test 
CompressedClassPointers.java on Windows.  The test checks that the base 
of the compressed class region is at a specific address. But, it fails 
intermittently because ASLR sometimes causes a different address to be 
returned.

The change was tested by checking, in Mach5, that the test was not run 
on Windows but was run on other platforms.

Thanks, Harold
