[OE-core] [poky] Early image startup

[Hatle, Mark]

As for the rpm ordering this was preserved from an earlier version.  If there is a more appropriate place to run the late configuration scripts, let's move it.  I think that it's likely a good place to move it to soon after the filesystem has been mounted RW.  Do any of the scripts normally require networking or other system resources?
