bug#44390: Cuirass reports succesful builds as failed in /var/log/cuirass.log and cuirass-web reports them as scheduled

[Mathieu Othacehe]

Hello,

Cuirass commit 697fa14584551d9595cd042f1ffeba240e45a127 adds a
"--queue-size" argument.

With Guix commit 770fb659a62d8adab9a4ba7b44e2760722703879, Cuirass is
passed the "queue-size" argument, defaulting to 1.

Thanks,

Mathieu
