procd: remove procd-nand package
We always want to support staged upgrades now, so it's better to include upgraded into the main package. /lib/upgrade/nand.sh is moved to base-files. The procd-nand-firstboot package is removed for now, it may return later as a separate package. Signed-off-by: Matthias Schiffer <mschiffer@universe-factory.net>
