update/release: fix/simplify mtime handling
i wasn't getting the very first line of tar --version, so it wasn't doing the check properly. further sort the files by name within the tar archive. for reliability, don't bother using versiondate anymore: set a *fixed* date, and fixed timezone, to ensure that it works reliably for reproducible tarball creation.
