[PATCH] Do not perform cross-directory renames when creating packs

[Petr Baudis <pasky@suse.cz>]

A comment on top of create_tmpfile() describes caveats ('can have
problems on various systems (FAT, NFS, Coda)') that should apply
in this situation as well.  This in the end did not end up solving
any of my personal problems, but it might be a useful cleanup patch
nevertheless.

If this one gets dropped now, I don't intend pursuing it further.
