[drlvm][kernel test] ObjectTest needs to be included back to test runs

                 Key: HARMONY-2294
                 URL: http://issues.apache.org/jira/browse/HARMONY-2294
             Project: Harmony
          Issue Type: Bug
          Components: DRLVM
            Reporter: Elena Semukhina

ObjectTest has been excluded from test runs some time ago. It occasionally failed on Windows
on testWaitlongint() and testWait1() .

I ran this test iteratively on drlvm and RI and found out that it failed on both VMs in the
same way and with appoximately equal frequency.

I fixed the test so that it passes on RI. The test passes on DRLVM too now.

1) testWaitlongint(): When failed, it always reported that it waited 499 ms instead of 500.
I allowed the test to accept 1 ms less waiting time.

2) testWait1(): it reported that InterruptedException has not been thrown while the waiting
thread was interrupted. Actually it failed very rarely (once per 1000 runs). I think this
happens because the test does not correctly wait for the thread's run() method start. Fixed.

3) I added a minor fix to thread_native_condvar.c so that nanoseconds are rounded up rather
than down.

I ran the test iteratively on linux / Win XP / Win 2003 / jet, opt, int and have not seen
a failure for a long time. The record is 4000 runs on Win 2003 / jet.

I think the test should be included back to test runs.
