* jq: 1.5 -> 1.6 (!!)

(last release was in 2015! :))

* jq: drop darwin patch, appears resolved by upgrade

commit history isn't that long, and has a few addressing
behavior on osx re:strptime-- and since this patch
doesn't apply it seems likely it's been resolved
but probably can be checked by any interested folks w/darwin.
