[bug#31813] [PATCH] evaluate: Use a generic key to identify Cuirass arguments.

[Mathieu Othacehe <m.othacehe@gmail.com>]

Hi,

Thanks to this patch, we are able to build on Cuirass guix package from
multiple source repositories (guix-modular-url1, guix-modular-url2, ...)

and then guix pull --url=url1 or guix pull --url=url2

Cuirass + new "guix pull" is becoming awesome, can't wait to have a
nice web interface :)
