torture: Report diagnostics from qemu
The current script does record qemu diagnostics, but the user has to know where to look for them. This commit therefore puts them into the Warnings file so that kvm-recheck.sh will display them. This change is especially useful if you are in the habit of killing the qemu process when you realize that you messed something up, but then later on wonder why the process terminated early.
