CI: retry macOS libANN installation up to 2× on failure

libANN availability seems erratic, with Macports sometimes reporting:

  Error: Port libANN not found

only for a retry of the job to succeed. This change introduces an auto-retry
loop on libANN’s installation, hoping this will ameliorate the issue.
