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) Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
