bitbake: cache: Add better cache loading sanity checks 

We've seen cache corruption where the pairs come out in a different
order to the way we saved them for unknown reasons. Add better sanity
checking to give a more user friendly error rather than a crash/traceback.

Also allows the system to reparse and recover.

(Bitbake rev: 4be4a15491530bd6dc018033ad3d4b2562ab6e23)
