  [FFe] Seed pemmican

Status in pemmican package in Ubuntu:
Status in ubuntu-meta package in Ubuntu:
  Fix Released

Bug description:
  [ 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 

  On the Pi 5 specifically:
  * Boot the image normally
  * Ensure boot proceeds normally with package installed and that no warnings 
  * Using bench power-supply to back-feed the Pi, lower voltage until brownout 
  * 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.
