[PATCH v2 1/6] meta: Move 'do_fetch' and 'do_unpack' to base-class

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

Issues:
unpack and fetch can only be used if you inherit dpkg, they should be
available to others i.e. classes and images

Change:
Pull the code out of the dpdk-class and stick it into the base-class. It is the
same code, no changes to it.

Impact:
This patch does not change the behaviour of Isar. It addresses the
issue, preparing for future patches.
