ext/openssl: drop support for OpenSSL 0.9.6/0.9.7

The last release of OpenSSL 0.9.7 series was over 9 years ago (!) and
even 0.9.8/1.0.0 are no longer supported (EOL was 2015-12-31).

It actually doesn't compile since r40461 (ext/openssl/ossl_bn.c
(ossl_bn_initialize): allow Fixnum and Bignum. [ruby-core:53986]
[Feature #8217], 2013-04-25, 2.1.0) and it looks like nobody noticed it.
