[PATCH v2] meta/dpkg-raw: do_install into a fresh directory every time

[Henning Schild <henning.schild@siemens.com>]

Permission problems revealed that we always packaged the sum of possibly
many rebuilds and maybe recipe versions. do_install should always start
working on an empty $D to ensure that the package only contains output
of the current build.
