tar "xattrs op not permitted" error in octave_app_diagnostic_dump on newer macOSes

[apjanke]

On new macOS, octave_app_diagnostic_dump is having trouble with tar and xattrs or permissions. Maybe it's specific to being run outside an actual Octave.app app bundle location.

On macOS 14 (on eilonwy), in a brewed installation of octave-octapp@8.3.0 (not an actual Octave.app):
