Richard AlpeandJoachim Wiberg 63a34d570d Use default pwd hash from VPD in QEMU
This commit does several things. Its end goal is to fetch the admin
password hash from VPD memory during factory bootstrap.

To accomplish this probe creates a new file /run/system.json with
information read from a fw_cfg QEMU partition. The data from
/run/system.json is then later used during config bootstrap to fill in
the factory administrator password.

The idea is to make QEMU behave the same way hardware does, i.e. a
default/factory password should be fetched and used from
"hardware memory". The hardware portion of this is yet to be done.
