In modern Poky the facade is gone and the data dictionary needs
to be accessed directly. This commit is catching up with it. It
was build tested on dora as well. I have not checked if it is
changing the checksums of a dora build.
For the IDU we currently want to have persistent log files. We
need to fork the volatiles script (installed as 00_core) and it
is already different between dora and current master of poky.
We are missing an sob-idu-qa check that verifies that /var/log
is not a symlink and that /etc/systemd/system/journald.conf is
set to persistent too.
