Comment (by jmroot):

 Purging the disk cache for the whole system is a pretty big hammer. Do you
 know if the ffmpeg file was bad in the port image or only in the archive
 that was deployed?

 Since #69555 we no longer store port images as archives on APFS systems,
 however we still create the image by running the destroot through tar in
 order to get HFS compression. Also that means the files go through tar
 twice on the buildbot, since an archive has to be created from the image
 to be deployed onto the packages server. For the latter step, we could
 arrange for gnutar to be installed in a different prefix on all the APFS
 build workers.
