cmd/doc: ensure functions with unexported return values are shown

Browse source 
The commit in golang.org/cl/22354 groups constructors functions under
the type that they construct to. However, this caused a minor regression
where functions that had unexported return values were not being printed
at all. Thus, we forgo the grouping logic if the type the constructor falls
under is not going to be printed.

Fixes #16568
