Remove a few files from the pytype blacklist. (#1628)

Fixes the following issues:

* Literals rather than ... for default values
* None rather than ... for default value of typed variable
* Literals rather than ... # type for top level constants
* # Foo rather than # type: Foo
* return value of init not set to None
