mkDataConRep: fix bug in strictness signature (#14290)
The strictness signature for a data con wrapper wasn't including any
dictionary arguments, which meant that bangs on the fields of a
constructor with an existential context would be moved to the wrong
fields. See T14290 for an example.
Test Plan:
* New test T14290
* validate
