Provide whitelist parity for MagicMock and Mock (#342)

* Provide whitelist parity for `MagicMock` and `Mock`

There are whitelist entries for the `return_value` and `side_effect`
attributes of the `unittest.mock.Mock` class. This change seeks to
provide parity for the `unittest.mock.MagicMock` class, which is just a
subclass of `Mock` but with default implementations of most of the magic
methods.
