bitbake: cookerdata: Convert multiconfig to use BB_CURRENT_MC 

People are struggling with multiconfig as the point the conf file
is injected into the data store is not what people expect. We can't
really use a post config since that is too late and we can't really
use a pre config file since that is too early. In OE terms, we need
something right around the local.conf point so it behaves in a similar
way.

A way to handle this is to set the new variable BB_CURRENT_MC to be the
currently selected multiconfig, then the metadata itself can choose
when to inject the approriate configuration.

(Bitbake rev: 518b9015c2be8d3894277a8e54890d6f04d656c0)
