[GIT PULL] Landlock updates for v6.3

[Mickaël Salaün]

Hi Linus,

This PR improves documentation, and makes some tests more flexible to be
able to run on systems without overlayfs or with Yama restrictions.

Please pull this Landlock changes for v6.3-rc1 .  These commits merged
cleanly with your tree, and have been successfully tested in the latest
linux-next releases for a few weeks.

Regards,
 Mickaël
