[PATCH] 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.
