Stop renaming catalogs in alien cache

When using alien cache, do not rename the cached catalog file. This can cause race conditions between different clients sharing the cache, resulting in multiple unnecessary downloads of the file It's especially harmful on NFS. The renaming was for use with pinning on a managed cache, so it isn't needed for alien cache anyway.
