Fix compilation with OpenSSL prior to 1.1.x

Variable crypto_engine is used but not declared when build with OpenSSL later than 0.9.7 and prior to 1.1.0. It's also necessary to include <openssl/engine.h> for the declaration of ENGINE_cleanup() in the same cases. The related code looks like it might be left over and not actually used in mod_proxy.
