Still, the point of this patch is that I want to add -F into all the

iotests are broken for these image formats. Patch 2 is a lot harder to
write if we have to make our use of -F conditional on the image format in
question.
Hm... Maybe _make_test_img can insert/filter out -F depending on $IMGFMT?
I was hoping to avoid that, but yes, if that's what we have to do... :(
The complication is that even if I filter out -F from the command line
based on $IMGFMT, then I have conditional output (whether backing_fmt=
or the warning message is output), which means doubling the number of
expected output cases, or else adding a multi-line filter which is also
smart enough based on $IMGFMT to translate a warning on one line into an
addition of a faked backing_fmt= on the next line.
