    bitbake: cooker: Rename __depends in all multiconfigs
    
    The renaming of the __depends variable to __base_depends and file
    watches needs to occurs for all multiconfigs, not just the base config.
    Failing to do this for all multiconfigs will result in a huge increase
    in the size of the parsing cache (about 5x for a single mulitconfig)
    because all multiconfig caches will still depend on the base config
    files. This will also seen a similar jump in the amount of time required
    to load the parsing cache from memory, both because the cache is larger
    and because of explosion of additional existence checks that must be
    done for the base files.
