iotests: change supports_quorum to use qemu_img

Browse Source 
Similar to other recent changes: use the qemu_img() invocation that
supports throwing loud, nasty exceptions when it fails for surprising
reasons.

(Why would "--help" ever fail? I don't know, but eliminating *all* calls
to qemu-img that do not go through qemu_img() is my goal, so
qemu_img_pipe() has to be removed.)
