oe-publish-sdk: add script

Add a script to publish an extensible SDK that has previously been built
to a specified destination. This published SDK is intended to be
accessed by the devtool sdk-update command from an installed copy of the
extensible SDK.

e.g.
oe-publish-sdk <ext-sdk> <destination>
