procd: firstboot nand/ubi takeover support
it is now possible to flash a initramfs kernel and a sysupgrade tar file inside the ubi partition. on first boot, the takeover script will find the tar file, extract and finally sysupgrade it. this allows us to flash owrt/ubi images in a 2 phase setup using ODM webuis that are not ubi aware. this is needed by some mediatek and brokencom devices.
