Title:
  errors with mult-volume gadgets

Status in Ubuntu Image:
  In Progress
Status in ubuntu-image package in Ubuntu:
  Fix Released

Bug description:
  The logic is subtly different in the Python and Go versions of ubuntu-
  image for populating bootfs contents. With multi volume gadgets, only
  the system volume is processed by this function. This needs to be
  fixed and tested with the following gadget.yaml:

  ```
  volumes:
    pc:
