poky-bleeding: Update and rework

This distro setting has bitrotted quite badly but the idea remains
a good one. Try and improve things by:

* using a class and a list of recipes to make things more readable
* drop settings for recipes which no longer use git
* drop obsolete PREFERRED_VERSION settings
* add a provider switch to use linux-yocto-dev
* reword to avoid "package" confusion with recipe

The distro then builds and highlighted a number of matchbox
issues which other patches address and improve.
