Right now, all qemu-iotests output data into the same scratch directory,
and so each tests needs to be responsible for cleanup up its own files.

Have each test use 'scratch/$seq' as its temp directory, so the check
script can do simple cleanup of removing the whole temporary directory.

Thanks - I'll send a v3 with that change after a while, in case there are more
comments. Or if someone applies it to their branch, they can just fix up the
commit message if they want.


(Hmm... I guess also s/each tests/each test as well, to be grammatically
correct)
