Replace calls to qemu_img_pipe('map', '--output=json', ...) with this new function, which provides better diagnostic information on failure. Note: The output for iotest 211 changes, because logging JSON after it was deserialized by Python behaves a little differently than logging the raw JSON document string itself. (iotests.log() sorts the keys for Python 3.6 support.)
