bug#63413: Stop and restart builds in cuirass

(For clarity: s/stop/cancel/ above.)

I’m happy to report that this bug should be fixed in the snapshot
recently deployed on ci.guix.gnu.org.  The fix is here:

  
https://git.savannah.gnu.org/cgit/guix/guix-cuirass.git/commit/?id=12d79854ee7685b356a72ca374f2a90b8efe5903

Lemme know if it turns out to be a broken fix!

Ludo’.
