bitbake: siggen: Use lookup cache exclusively 

All the values we need are already guaranteed to be in the lookupcache
so rather than fetch variables again, just use the cache. This gives a
small performance improvement and simplifies the code.

(Bitbake rev: 8ffaba61da7f195d7c3b64dce35b6a56272aecae)
