[PATCH 1/1] classes/image-postproc: chroot before postprocessing /etc/machine-id

["alexander.heinisch via isar-users" <isar-users@googlegroups.com>]

From: Alexander Heinisch <alexander.heinisch@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.
