cbfstool: Rename cbfs_walk() to cbfs_legacy_walk() 

This function name clashes with cbfs_walk() in the new commonlib CBFS
stack, so rename it to cbfs_legacy_walk(). While we could replace it
with the new commonlib implementation, it still has support for certain
features in the deprecated pre-FMAP CBFSes (such as non-standard header
alignment), which are needed to handle old files but probably not
something we'd want to burden the commonlib implementation with. So
until we decide to deprecate support for those files from cbfstool as
well, it seems easier to just keep the existing implementation here.
