docs: use literalinclude for system requirements

The YAML variables for the host dependencies are updated by hand and
actually only used inside code blocks.

Let's migrate all instructions into separate shell scripts that are then
literalinclude'd into the Sphinx documentation.

This allows a few things:
- ability to run shellcheck on the scripts if we ever want to
- manually calling the appropriate script from a supported distro to
  build stuff (distro or bitbake/yocto stuff)
- use this script to create containers to do CI of documentation on
  different distros, to make sure our instructions are all up to date,
