Fix YAML folding compatibility and Linux arm64 OpenSSL linking

- Revert script block from |- (literal) back to > (folded) since the
  script was written for folded syntax
- Replace if/else/fi block with single-line && chain for Linux arm64
  OpenSSL, as multi-line if/else/fi gets mangled by YAML > folding
