mail/ruby-mime-types: update to 3.3.1

Update ruby-mime-types to 3.3.1.

## 3.3.1 / 2019-12-26

*   1 minor bugfix:

    *   Al Snow fixed a warning with MIME::Types::Logger producing a warning
        because Ruby 2.7 introduces numbered block parameters. Because of the
        way that the MIME::Types::Logger works for deprecation messages, the
        initializer parameters had been named `_1`, `_2`, and `_3`. This has
        now been resolved. [#146][]

*   Administrivia:

    *   Olle Jonsson removed an outdated Travis configuration option (`sudo:
        false`). [#142][]
