bug#41214: Pulling 1.0.0 fails while running ‘compute-guix-derivation’

["Ludovic Courtès" <ludo@gnu.org>]

From today’s Guix, where (default-guile) is 3.0, I can’t build 1.0.0:

The module in
/gnu/store/g29fabc57fkzimrf6gsb72fr7fq069yf-module-import-compiled were
built with 2.2.4, which is fine, but ‘compute-guix-derivation’ itself
runs on 3.0.

Probably ‘%quirks’ should also change (default-guile).
