Support build-drivers for linux 6.0

[FedeDP]

Motivation

Most of our build-drivers jobs are split for each kver; but we only support linux up to 5.X.

Feature

We should add linux 6.X support.

[FedeDP]

This is not super urgent because i think none of our supported distros actually ships kernels >=6.0.

[FedeDP]

Well, seeing recent kernel-crawler jsons, it seems like more and more distros are now on linux 6.x. We should really add support for it (but we might first want to investigate an expansion of our autoscaling group for the cluster)

[FedeDP]

Note: even if we now have jobs for kernels 6.x, note that supported driver versions still do not support linux >= 6.2 (eg: https://prow.falco.org/view/s3/falco-prow-logs/logs/build-new-drivers-ubuntu-gcp-6-postsubmit/1647885024428560384). List master (ie: next driver version, shipped with Falco 0.35) do support it. See relevant issues:
