serviceability/sa/ClhsdbDumpclass.java could leave files owned by root on macOS

When running the hotspot jtreg test serviceability/sa/ClhsdbDumpclass.java on a macOS that allows for passwordless sudo, the test will leave a file in the scratch directories that is owned by root and cannot be deleted by normal users.

On macOS the test start the class dump with sudo if possible. The dumped class file is owned by root and will be dumped to $JTwork/scratch/jdk/test/lib/apps/LingeredApp.class

The test will write a warning in the jtr file:
...
#section:script_messages
----------messages:(11/980)----------

I suggest to skip the test in case that sudo rights are available. That was already done for a similar test in JDK-8290687.
