classes/populate_sdk_ext: add a better config extension mechanism 

The sdk_extraconf() method of setting the configuration was awkward
since you needed to set it in a class and then inherit that class since
function definitions aren't allowed in conf files. It seemed to me the
a neater way to do this was to read the extra lines from an additional
conf file sdk-extra.conf (which can be located in a conf/ directory
anywhere along BBPATH as with other configuration files).

(From OE-Core rev: b53edb86c65ad375df153017f245244ef97f3932)
