bug#32955: Cuirass: Some tests depend on 'guix-current', which makes them resource expensive

Hello,

These tests are indeed expensive.  However the motivation here is
precisely to test a complete installation procedure using the current
Guix in the installation image.  If we were to change that we’d be
testing something different and much less interesting.

So I think there’s not much we can do here.

Does that make sense?

(Note that all the other system tests use just whatever snapshot the
‘guix’ package refers to, which is good enough for them because they
don’t test things where Guix itself is involved.)

Thanks,
Ludo’.
