Gather dependencies in poky.yaml.in

We used to have packages here and there in system-requirements.rst for
each distro. Instead, gather all the dependencies in poky.yaml.in so we
have an overview of what we provide for each distro.

Use yaml ">" to list the dependencies in alphabetical order, one entry
per line, which makes them easier to read and compare among distros.

Rename UBUNTU_… variables to UBUNTU_DEBIAN_…, since these are used for
both distros.
