Re-add build option to be enable some kind of custom builds

For example, with:

$ BASE_CONTAINER=ubuntu:focal-20211006@sha256:26c3bd3ae441c873a210200bcbb975ffd2bbf0c0841a4584f4476c8a5b8f3d99
$ NB_UID=1234
$ make build/base-notebook \
  ARGS="--build-arg BASE_CONTAINER=$BASE_CONTAINER --build-arg NB_USER=$NB_USER_TEACHER --build-arg NB_UID=$NB_UID"

we could generate base-notebook using a specific base image and where
jovyan is uid 1234 instead of 1000
