torture: Check for nul bytes in console output
When starting a new torture run while an old one is still running, both qemu processes can be outputting to the same console.out file. This can cause quite a bit of confusion, so this commit checks for this situation, which is normally indicated by nul bytes in the console output. Yes, if your new run uses up an exact number of blocks of the file, this check will be ineffective, but the odds are not bad. Signed-off-by: Paul E.
