Update ruby-faye-websocket to 0.10.9.
pkgsrc changes:
* Add "USE_LANGUAGES= # none".
* Update LICENSE to apache-2.0.
### 0.10.9 / 2019-06-13
- Use the EventMachine API rather than `IO#write` to write data; this uses the
event loop and avoids getting blocked by slow clients
### 0.10.8 / 2019-06-10
- In the case of a close timeout, don't block on waiting for writing to the
socket to complete
- Fix a race condition that caused a timeout not to be cancelled immediately
when the WebSocket is closed
- Change license from MIT to Apache 2.0
