[OE-core] [PATCH 14/14] devtool: build: support using BBCLASSEXTENDed names

[Paul Eggleton]

It's logical that you would want to build BBCLASSEXTENDed items
separately through devtool build, so simply allow that - we're just
passing the name verbatim to bitbake, so all it means is adjusting the
validation.
