dialyzer: Extend the map implementation's handling of ?unit
The Maps implementation handles ?unit in more cases.
Exactly when t_is_none_or_unit() is to be called is not clear to me.
The added cases are about a map type being ?unit, but the key or the
value of an association can also be ?unit, but that is not always
checked.
