TEST_BUG: com/sun/jdi/BreakpointWithFullGC.sh fails to cleanup in Cygwin

[Chris Hegarty]

Sorry Dan, I'll put a more complete description in the bug report.

This issue, from what I can tell only happens with very recent Cygwin 
versions. I'm running 1.7.9. When running the com/sun/jdi tests in a 
batch, in samevm mode, this test leave behind a file, NUL, in the 
scratch directory that cannot be deleted. This causes the remaining 
tests to also fail.

Thanks for the review,
-Chris.
