openssl: assume engine support in 1.0.1 or later
Previously it was checked for in configure/cmake, but that would then leave other build systems built without engine support. While engine support probably existed prior to 1.0.1, I decided to play safe. If someone experience a problem with this, we can widen the version check. Fixes #2641 Closes #2644
