bitbake: cache/siggen: Simplify passing basehash data into the cache

The basehash data is really internal bitbake data and passing an object
directly is more efficient than creating and then extracting variables.

This will match the format of other data we may optionally wish to
store in the cache so more to the more efficient method. Nothing I
can see is using this data today (and nothing should be).
