Unittest uses unique test db name (#8124)

Browse Source 
Summary:
thread_id is only unique within a process. If we run the same test-set with multiple processes, it could cause db path collision between 2 runs, error message will be like:
```
...
IO error: While lock file: /tmp/rocksdbtest-501//deletefile_test_8093137327721791717/LOCK: Resource temporarily unavailable
...
```
This is could be likely reproduced by:
```
gtest-parallel ./deletefile_test --gtest_filter=DeleteFileTest.BackgroundPurgeCFDropTest -r 1000 -w 1000
```
