base.bbclass: use debug messages for INCOMPATIBLE_LICENSE
Spamming potentially over a screenful of messages due to their
INCOMPATIBLE_LICENSE selection seems a bit unnecessary. If the distro was
configured that way, the user likely won't care, and if the user set it, they
likely know the implications, so make the messages debug instead.
