Sascha Silbe 0145b4e130 qemu-iotests: check: don't place files with predictable names in /tmp 
Placing files with predictable or even hard-coded names in /tmp is a
security risk and can prevent or disturb operation on a multi-user
machine. Place them inside the "scratch" directory instead, as we
already do for most other test-related files.
