There is a problem with the existing sstate checksums since CCACHE itself is not being excluded, only CCACHE_DIR so you'd end up with sstate built using ccache and sstate built without using cccache with different checksums. This change unifies those to have matching sstate checksums. So with and without use of the class, the checksums should now be the same.
