ci: fix dmg release artifacts

- build-release.py: use absolute paths instead of resolved paths
- xcode: run the shell script with 'set -ex' for extra verbosity +
  failing when an error happens
- On macOS ci, /tmp resolves to /private/tmp, causing the shell script
  to not find the SDL3.xcframework. So don't  use /tmp.
