[PATCH v3 3/3] gitlab: enable a very minimal build with the tricore container

[Alex Bennée]

Rather than base of the shared Debian 10 container which would require
us to bring in even more dependencies just bring in what is needed for
building tricore-softmmu in GitLab. We don't even remove the container
from the DOCKER_PARTIAL_IMAGES lest we cause more confusion.

v3
  - make a uni-container (but not based from common code)
