update: fix edge-case with update.atomic-file and read-only files

We used to create the tempfile with the original file mode. That means
creating a read-only tempfile when the original file is read-only, which crash
if we need to write on the tempfile.

The file in the working directory ends up being writable with and without the
atomic update config, so the behavior is the same.
