crypto_openssl: add initialization to pick up local configuration

crypto_openssl: add initialization to pick up local configuration

The test programme for the new openssl engine code requires overriding
the system default configuration file to point to the location of the
test engine.  Add an initialization stanza that makes this behaviour
universal, so now anyone running openvpn configured with openssl can
specify their own configuration file with the OPENSSL_CONF environment
variable.
