Support for the -d and -p options is dropped; it may be added again at some
point by adding these flags to the ubus sysupgrade call.
A downside of this is that we get a lot less information about the progress
of the upgrade: as soon as the actual upgrade starts, all shell sessions
are killed to allow unmounting the root filesystem.

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.
