Remove paths from _eclasses_ serialization in the cache. This makes the mtimes of the eclasses the only thing that distinguishes them, but the probablility of collision is negligible. This same _eclasses_ format will be used to serialize eclass mtimes in cache that is distributed via the rsync mirrors. The deserialization code can handle mixtures of both the old and new formats.
