This changes `-chardev stdio` to `-chardev file` and uses a temporary file to communicate with QEMU. This fixes an issue where `-chardev stdio` hangs if `STDIN` is not a TTY. I could not figure out how to make it work without a TTY, and it does not print any meaningful diagnostics. Problem is, in CI and other automated runners, we do not necessarily have a TTY as STDIN. This just switches to a temporary file, which seems to work under all circumstances.
