Paul Dagnelie 8100e476ea Add more DDT tests
The new Fast Dedup feature has a lot of moving parts, and only some of
them have tests. We have some tests for prefetch and quota, and a
generic ZAP shrinking test, but we don't have anything for the pruning
command or specific to DDT zap shrinking. Here we add a couple small new
tests for zpool ddtprune and DDT-specific ZAP shrinking.
