avoid validate/delete/load race in cache generation
Keeping the Fd of the cache file we have validated around to later load it into the mmap ensures not only that we load the same file (which wouldn't really be a problem in practice), but that this file also still exists and wasn't deleted e.g. by a 'apt clean' call run in parallel.
