twinkie: build a combined firmware
Build a Twinkie firmware image with the regular Twinkie sniffer firmware
in the RO partition and a firmware behaving as a USB PD sink in the
RW partition.
The user can call the "twinkie sink" command to switch the USB PD sink
firmware in the RW partition (and call "reboot" if he changes his mind
and wants the sniffer back).
Restore the ability of building different tasklists which was broken
where the tests build was simplified.
