RFR: 8052403 java/util/logging/CheckZombieLockTest.java fails with NoSuchFileException

[Daniel Fuchs]

Please find below a fix for

8052403: java/util/logging/CheckZombieLockTest.java fails
          with NoSuchFileException
https://bugs.openjdk.java.net/browse/JDK-8052403

The issue here is that CheckZombieLockTest and CheckLockLocationTest use
(create and delete) the same writable-dir under /tmp.

When jtreg is run with a high concurrency factor this sometimes results
in one of the tests deleting the directory that the other is
running. I could verify this by triggering the same failure with:

    jtreg -verbose:all -jdk $MYJDK -conc:12 \
                      jdk/test/java/util/logging/Check*


The fix simply arranges for CheckZombieLockTest to use a different
directory than that used by CheckLockLocationTest (and also improves
the diagnostic by arranging for setUp() to fail fast if the test
lock file cannot be created).
