[OE-core] [PATCH] insane.bbclass: Warn if ${COREBASE}/LICENSE is used

[Saul Wold]

The top level LICENSE file is not actually a license, it refers
other licenses that are used by Bitbake and Meta-data. Relying
on this file could cause problems for recipes when this file
changes, which it is about to.
