easyrsa_openssl() default behaviour is to re-use the generated
safe SSL config file, after bieng called for the first time.
NOTE: easyrsa_openssl() is a heavily nested function.
This option forces recreation of a safe SSL config file for each
call to easyrsa_openssl().
Only effective when an SSL config fie is required.
