Same with ‘guix publish’: https://issues.guix.gnu.org/74632

I’m not sure when these started to happen for ‘guix publish’.

Data point: the ‘guix publish’ instance at guix.bordeaux.inria.fr never
encountered this problem.  The main difference compared to ci.guix is
that it does not produce lzip archives.  (I see the Coordinator uses
Guile-Lzlib; maybe that’s a lead.)
