[Bug 2062564] [NEW] [FFe] Seed pemmican

[Dave Jones]

Public bug reported:

[ Impact ]

Add pemmican to raspi server and desktop images in order that Pi 5 users
can be notified if/when overcurrent or undervolt events occur
(potentially resulting in brownout, data-corruption, and all manner of
other symptoms typically caused as a result of undervolt).

[ Test Plan ]

On all supported models of Pi:
* Boot the image with pemmican installed
* Ensure boot proceeds normally with package installed and that no warnings appear

On the Pi 5 specifically:
* Boot the image normally
* Ensure boot proceeds normally with package installed and that no warnings appear
* Using bench power-supply to back-feed the Pi, lower voltage until brownout occurs
* Reboot and ensure undervolt warning is shown
* Shutdown and boot with PSU that cannot negotiate 5A
* Ensure deficient PSU warning is shown

On the Pi 5 desktop image specifically:
* Boot desktop image
* Attach USB load tester and raise current draw until USB ports fail
* Ensure overcurrent warning is displayed

[ Regression Potential ]

Quite low given all the tests noted above have already been performed on
all supported models.
