[PATCH v2] classes/image-postproc: chroot before postprocessing /etc/machine-id

[alexander...@siemens.com]

From: Alexander Heinisch <alexander...@siemens.com>

If /etc/machine-id happens to be a link to e.g. /var/...
the postprocessing overrides build-hosts /var/... instead of
the desired file on the rootfs.
