bug#38232: Cuirass: Some builds fail although their log file ends with 'build-succeeded'

[Mathieu Othacehe]

Hello,

It seems to be also an issue for evaluations that look successful but
are reported as failed, see here:

https://ci.guix.gnu.org/eval/8641/log/raw -> mark as failed
https://ci.guix.gnu.org/eval/8725/log/raw -> mark as failed

Mathieu
