OPENSSL_config(): restore error agnosticism
OPENSSL_config(): restore error agnosticism

Great effort has been made to make initialization more configurable.
However, the behavior of OPENSSL_config() was lost in the process,
having it suddenly generate errors it didn't previously, which is not
how it's documented to behave.

A simple setting of default flags fixes this problem.

Fixes #8528
