Bug Description

It is currently impossible to build rpm based image in the container, since rpm-distro/cleanup.d/99-selinux-fixfiles-restore tries to execute `runcon` on chroot which will not work in container, since selinux is disabled there:

(app-root) runcon -t setfiles_mac_t -- /opt
runcon: runcon may be used only on a SELinux kernel
(app-root) sestatus
SELinux status: disabled

`disk-image-create fedora-28 vm` fails because of that.

It is generally not very nice to create images in container, but I am trying to containerize Zuul, which uses diskimage-builer, so I face this problem

Facing a similar issue using bifrost stable/queens, which builds images within a docker container. Disk Image Builder is failing with:

`kauditd not found, suggesting auditing support is disabled in the host kernel. setfiles will fail without this, please enable and rebuild`

even though the call to setfiles actually succeeds if you comment out the check that causes this:

presumably runcon is set to ""?

It's unclear which diskimage-builder release the original issue was using. Since commit the script should correctly identify that SELinux is disabled and set _runcon to an empty string.

    Fail build due to missing kauditd only when SELinux is enabled

    With the check added in commit 7566819139e31c95038f9f1c39a2995d1fc93c17,
    diskimage-builder fails to build RPM-based images if kauditd is not
    running. However, this is only valid for environments where SELinux is
    enabled. If SELinux is disabled (which is identified by an empty _runcon
    variable), proceed with running setfiles.
