feature/buster FTBFS when building in RAM: mksquashfs is killed

I’ve compared the list of included packages with what we have on Tails
3.x and there’s nothing obviously wrong in there. So it looks like we’ll
need to bump BUILD_SPACE_REQUIREMENT
or similar.
Next step: try with noram
to check if we only need more RAM.
