cmake: dedupe crypto-backend detection
Before this patch CMake did crypto-backend detection in both `src/CMakefiles.txt` and `tests/CMakefiles.txt`. Merge them and move it to the root `CMakefiles.txt`. While here, also add zlib for OpenSSL. Necessary when using OpenSSL builds with zlib enabled. Closes #905
