bug#76802: 31.0.50; Error when installing/activating packages due to emacs-version mismatch

[Tassilo Horn]

When I start emacs with the current master (2dea3a0d34859852d3577), I
get errors like this one when activating, installing, or updating
packages.  Obviously, I'm using emacs 31 so I shouldn't get errors that
a package requires (at least) emacs 27.1.

I think the commit that broke things is 5dd8b7e75259663415523f3ebe by
Stefan Kangas (in Cc).  I've checked out 5dd8b7e75259663415523f3ebe^ and
things are working smoothly again.
