share: properly copy cache files when cloning from a share
If a is shared to b and b cloned to c, the old code would look directly
under b/.hg for the cache directory and not use the cachevfs layer to
pick the members from a/.hg/cache. Adjust variable names and comments to
reflect that the function is used for more than just the branchmap
cache.
