qa: krbd_exclusive_option.sh: fixup for json.tool ordering change

In Python 3.5 json.tool was changed to produce unsorted output and
--sort-keys option was added to compensate.  This wasn't caught by
4fe245cc2f2d ("qa: update krbd tests for python3") because it raced
with 50933b863a1d ("qa: krbd_exclusive_option.sh: update for recent
kernel changes").
