bitbake: siggen: Optimise get_unihash disk based cache handling
Currently the cache can grow huge since any previously used hash is
retained in the cache. This change moves to use one hash per task
which improves the speed of the functions considerably. Currently
performance is an issue, as are very large cache files and cache
load time.
By moving to a single hash per task, the shorted filename as a key
is no longer usable as the same recipe has multiple variants for
the same filename so this has to change.
