[CI] Make the hdiutil retry wrapper report failure (#7643)

* [CI] Make the hdiutil retry wrapper report failure

CPack reads the wrapper's exit status to decide whether the disk image was
created, so a zero exit turns a failed hdiutil into a later "Problem copying
the package" error that hides hdiutil's own message.

- Propagate hdiutil's real status instead of collapsing every failure to 1.
- Name the failing subcommand (create/attach/detach/convert) so the message
  says which CPack step gave up.
- Count attempts rather than failures in the retry line.

* Update .ci/compile.sh
