[PATCH 7/7] license_image.bbclass: Report only the licenses that are incompatible

[Peter Kjellerstedt <peter.kjellerstedt@axis.com>]

Instead of reporting ${LICENSE} when a package cannot be installed
into an image because it is using an incompatible license, report the
license(s) that are actually incompatible.
