Aravind Ramesh 9c932816cf db_stress: db_stress segmentation fault (#9219)
Summary:
db_stress asserts/seg-faults with below command (on debug and release builds)

```
"rm -rf /tmp/rocksdbtest*; db_stress --ops_per_thread=1000 --reopen=5"
=======================================

Segmentation fault
=======================================

```
StressTest() constructor deletes the directory "dbstress" because
the option --destroy_db_initially is true by default in db_stress.

This Seg fault happens on a new database, UniqueIdVerifier's constructor
tries to read the ".unique_ids" file, if the file is not present,
ReopenWritableFile() tries to create .unique_ids file, but fails
as the directory db_stress is not available. The data_file_writer_
is set as an invalid(null) pointer and in subsequent calls (~UniqueIdVerifier()
and UniqueIdVerifier::Verify()) it accesses this null pointer and crashes.

This patch creates db_stress directory if it is missing, so the .unique_ids file
is created.
