Make the minimum debootstrap version configurable, or enforce a minimal version instead of an exact version

[ferrarimarco]

Hi!

scripts/install_dependencies.sh currently enforces an exact debootstrap version. I assume that's to use a known-good one. I containerized my build toolchain, so I enforce a debootstrap version when building the container image.

Is it possible to restore the minimal debootstrap version check behaviour, or at least make it configurable (while still setting a known-working default) with a parameter (in the build configuration perhaps)?

Thanks!
