script/build-with-container: add more detailed variants
Create two new variants 'packages.minimal' or 'packages.crimson'.
The first disables test deps (make check) and crimson deps.
The second only disables test deps and explicitly enables crimson deps.
The existing 'packages' variant now tries to determine if it should
switch to 'packages.minimal' or 'packages.crimson' by checking for
the same env vars install-deps.sh was (WITH_CRIMSON).
