dialyzer: Warn for bad type variables of parameterized types
As of commit 854ee8b (Erlang/OTP 18) warnings about using '_' as type
variable in parameterized types have not been output.
The code of erl_types:t_var_names() is corrected. The spec is also
corrected (thanks to Kostis for pointing out the bug).
