Improve obsolete_files_test (#5125)

Browse Source 
Summary:
We see a failure of obsolete_files_test but aren't able to identify
the issue. Improve the test in following way and hope we can debug
better next time:
1. Place sync point before automatic compaction runs so race condition
   will always trigger.
2. Disable sync point before test finishes.
3. ASSERT_OK() instead of ASSERT_TRUE(status.ok())
