Not sure why but when you try to build c9s with rpm-ostree from
git main the change in [1] causes the sed commands here to exit
with a weird error:
```
sed: couldn't close stdout: Bad file descriptor
```
Let's just redirect to /dev/null for now and maybe we can drop
it longer term when c9s goes away. See also [2] where this was
reported.
