The following should override it globally. (e.g. added to .emacs)

 (assoc-default "application/zip" mm-inline-media-tests #'string-match nil)
 (list #'mm-archive-dissect-and-inline (lambda (handle) nil)))

I only tested with "application/zip" replaced by
"application/x-tar-archive", but the principle should be the same.

I'm not really sure the right way of handling this as a default. It's
always a bit tricky with configuration shared with gnus.
