* Fix ssl_v3_rejection test hanging
When closing the server, puma would get caught in a loop where it would
expect IO.select to timeout but instead it would return a file
descriptor ready to read, but in a end-of-file condition.
* Remove windows tweaks from test_puma_server_ssl.rb
So that the hang I'm getting when running the tests locally can be
reproduced.
* Add missing appveyor entry
* Try fix 2.2.9 build
* Fix extra package installation on appveyor
