openssl: always build with GOST engine support

The packages feed has a proposed package for a GOST engine, which needs
support from the main openssl library.  It is a default option in
OpenSSL.  All that needs to be done here is to not disable it.

Package increases by a net 1-byte, so it is not really really worth
keeping this optional.

This commit also includes a commented-out example engine configuration
in openssl.cnf, as it is done for other available engines.
