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
