fsl-eula-unpack.bbclass: Enhance EULA model

Each new version of the EULA is meant to be a click
through that includes any existing packages with an
older EULA. The latest EULA is also copied in the
layer.

Capture this model in the class by listing the
known EULAs and checking that any package
has a known EULA. The new model also allows
extensibility, so new EULAs can be introduced
separately.
