Unable to build kernel module for Ubuntu AWS with 5.11.x kernels (GLIBC_2.33)

Describe the bug

Some recent images require a version of GLIBC that is newer than the one shipped with our standard build image. To fix this, we may need to use different Docker images to build different kernels.

How to reproduce it

Try building this image: https://github.com/falcosecurity/test-infra/blob/master/driverkit/config/17f5df52a7d9ed6bb12d3b1768460def8439936d/ubuntu-aws_5.11.0-1008-aws_8.yaml

./driverkit docker -c config/3aa7a83bf7b9e6229a3824e3fd1f4452d1e95cb4/ubuntu-aws_5.11.0-1008-aws_8.yaml --driverversion 3aa7a83bf7b9e6229a3824e3fd1f4452d1e95cb4 --timeout 1000 -l debug
