bitbake: bitbake: cache: Cache size optimization

Now that there is a cache object per multiconfig, it is not necessary
for each cache object to parse all other multiconfigs. Instead, each
cache now only parses the files for it's multiconfig.

(Bitbake rev: 3c5c7346adf4ca7ec761c08738f12401ba75b7c8)
