parentqemu-img: Print available options with -o ? (diff)

Update the documentation to reflect the introduction of format specific options with -o. Don't advertise -e or -6 any more, they exist only for compatibility reasons and can be replaced by the corresponding -o options. Signed-off-by: Kevin Wolf <>
