Bug#1139500: reprotest: num_cpus fails when there's offline cpu

[Tianyu Chen]

Package: reprotest
Version: 0.7.30
Severity: normal
X-Debbugs-Cc: sweetyfish at deepin.org

Currently, running reprotest inside a container randomly fails due to
$CPU_LIST passed to taskset -a -c sometimes contains a offline cpu.

In my case, I'm running reprotest inside a incus container. I launched
the container with -t c8-m32.

Thanks!

Best regards,
