Ensure the tests pass even if the default seclevel has been changed

Ensure the tests pass even if the default seclevel has been changed

The compile time default TLS security level can be changed if the user
sets `-DOPENSSL_TLS_SECURITY_LEVEL=x` at configure time (where "x" is some
number, typically 0 or 1).

Since OpenSSL 3.4 tests are failing if the default security level is 0. We
fix the tests for this case.

Fixes #26255
