iotests: Add -display none to the qemu options

Without this argument, qemu will print an angry message about not being
able to connect to a display server if $DISPLAY is not set.  For me,
that breaks iotests.supported_formats() because it thus only sees
["Could", "not", "connect"] as the supported formats.
