Only run secondary db verification for blackbox crash tests

[archang19]

Summary

This is a continuation of #13338, which aims to address crash test failures caused by #13281.

I looked through the test failures again, and they all are for the whitebox tests.

I am pretty sure this is because the whitebox tests have 20 for reopen whereas the blackbox tests have 0 inside whitebox_default_params and blackbox_default_params.

The error logs for the ASAN and TSAN failures point to the ReOpen method, so I think that if we just avoid this code path, we can avoid the failures.

I do not think that the whitebox tests give us additional information for the sole purpose of secondary DB verification compared to the blackbox tests. Thus, I think it is likely better to just enable secondary DB verification on blackbox tests only. We still will want to monitor for data verification failures and see no verification failures for an extended period of time.

Test Plan

Monitor recurring crash test runs.

I confirmed the simple blackbox test can give 1 for test_secondary.

python3 tools/db_crashtest.py --simple blackbox 

whereas test_secondary is not even specified in

python3 tools/db_crashtest.py --simple whitebox
