base.bbclass: Note when including pn with INCOMPATIBLE_LICENSES
We need to be able to tell people if we WHITELIST a recipe
that contains an incompatible licese.
Example: If we set WHITELIST_GPL-3.0 ?= "foo", foo will end
up on an image even if GPL-3.0 is incompatible. This is the
correct behaviour but there is nothing telling people that it
is even happening.
