Fix app-defined privileges certificate verification

Fix app-defined privileges certificate verification

Since OpenSSL 3.0 a number of additional checks introduced to X509_verify_cert()
according to requirements in RFC 5280 in case X509_V_FLAG_X509_STRICT is set.
For example, the basicConstraints of CA certificates must be marked critical.

This checks cause verification failure for not well-formed certificates.
Having backward compatibility in mind, it's better to disable strict checking
than replacing all broken certificates in applications.
