Mirrors / Yocto Git Mirror (push) Waiting to run

Details

Upgrade to Ubuntu 22.04 because it is compatible with the Yocto
Project release Walnascar and provides a newer Python version:
- Add --ulimit "nofile=1024:1048576" to yocto-builds.yml.
- Increase vm.max_map_count.
- Add --security-opt apparmor=unconfined to docker cmdline.
- Run docker without the default seccomp profile

This commit is backport from branch master to Scarthgap because
Ubuntu 20.04 reached its end of life (EOL) on May 31, 2025. Yocto
release Scarthgap also supports Ubuntu 22.04.
