Now that the QMP output visitor supports an explicit null
output, we should utilize it to make it easier to diagnose
the difference between a missing fdt vs. a present-but-empty
one.
(Note that this reverts the behavior of commit ab8bf1d, taking
us back to the behavior of commit 1d10b44; but that this time,
the change is intentional and not an accidental side-effect.)
