This has an issue where untaring will mess up the extracted dir entry timestamps in a few cases, where our manual sort skews entry order. This can be avoided by using `--delay-directory-restore` on extraction.

old-linux failure is unrelated. Not sure why it affects this PR though (this is not based on the commit that seems to be causing it). |

In the initial implementation of reproducible tarballs, they were
missing directory entries, while .zip archives had them. It meant
that on extracting the tarball, on-disk directory entries got the
current timestamp.
This patch fixes this by including directory entries in the tarball,
with reproducible timestamps. It also moves sorting inside tar,
to ensure reproducible directory entry timestamps on extract
(without the need of
--delay-directory-restoreoption, whenextracting with GNU tar. BSD tar got that right by default.)
--sort=option was introduced in GNU tar 1.28 (2014-07-28)Ref: #13299 (comment)
Follow-up to 860cd5f #13299
Closes #13322
