[PATCH 13/18] iotests/091: Use _cleanup_qemu instad of "wait"

[Max Reitz]

If the test environment has some other child processes running (like a
storage daemon that provides a FUSE export), then "wait" will never
finish.  Use wait=yes _cleanup_qemu instead.

(We need to discard the output so there is no change to the reference
output.)
