openqa/worker: override kernel scheduler config

This applies only within Fedora infra for now, as we're not sure
whether worker hosts on different hardware hit this bug. It's
intended to work around:
https://bugzilla.redhat.com/show_bug.cgi?id=2009585
a bug which results in the infra worker hosts hanging after a
short time when running kernels newer than 5.11.
