feat(jobspec): improve tput selection

+ Revert bad edit on 2n-dnv, add 1518b back.
+ Add 1c ip4base tput everywhere nat44ed tput is tested.
 + Both tcp and udp.
+ Use only 1c tests for ip4base tput.
+ Use the same selection in mrr as in mlr.
- 2n-tx2 and 2n-zn2 still have no ASTF tests.
- ASTF tests still only tested on xxv710, no 100ge tests yet.
