dockerfiles: reorganize for recursive rebuilds

prerequisite for recursive rebuilds of images on changes.
Use the command "tree" to make sense of the new layout:

|   `-- ./trusty-amd64-tcwg-base/trusty-amd64-tcwg-dev

    `-- ./xenial-i386-tcwg-base/xenial-i386-tcwg-build

Notes:
- ci-base- images are not handled here
- relative paths in tcwg builds have been adjusted
- tcwg jobs also build their parents recursively. This hasn't been
  touched in this commit, but we'll probably want to optimize the CI
