Subject: [PATCH] Send binary frame in websocket client

Websockify 0.9.0 rejected receiving text frame:
https://github.com/novnc/websockify/commit/8eb5cb0cdcd1314d6d763df8f226b587a2396aa2
We have to switch to binary frame instead.

Change-Id: I2677b8879ccb27def22126811c347d5c08f5aada
Closes-Bug: #1847889
