ad9c391e3f QSSB_FS_ALLOW_WRITE does not imply ALLOW_READ anymore
Landlock can handle write access without it implying read access,
in contrast to the existing bind mounts solution. Hence, remove
ALLOW_READ from ALLOW_WRITE bitmask.

6e6812e13d Introduce mount_path_policies_to_chroot option, changing path_policy enforcement logic
Previously, we needed chroot and bind mounts to enforce path_policies. Therefore,
in the presence of path policies, we had to explicitly create a chroot
dir.

With the coming landlock support, this is not required anymore.

However, one might still want to chroot and bind mount flags. But
path policies don't dictate that anymore.
