That's a heavy sledgehammer, that has the potential to affect a lot of
other programs called alongside qemu-img.  Simpler would be to just pass
-- in the command line at the point where you want to force qemu to
treat all further arguments without getopt reordering them, as in:

$QEMU_IMG -- create -f $IMGFMT $extra_img_options $TEST_IMG $image_size
