[PATCH 5/6] Fix "git-local-fetch -s" with packed source repository

"git-local-fetch -s" did not work with a packed repository, because symlink() happily created a link to a non-existing object file, therefore fetch_file() always returned success, and fetch_pack() was not called. Fixed by calling stat() before symlink() to ensure the file really exists.
