ci: Try reducing FD soft limit to fix valgrind tests

```

I’m not really sure what that means, but `show-execution-environment.sh`
says the FD soft limit is set to 524288 on the CI machine. That seems
high; on my machine it’s only 1024 (and the valgrind tests pass). So
let’s try 1024.

The valgrind CI has been failing since we most recently upgraded the CI
image to a new version of Fedora.
