Revert of Remove Android x86 compilation trybot from CQ. (patchset #1 id:1 of https://codereview.webrtc.org/1959923002/ )

Reason for revert:
https://codereview.chromium.org/1985413002/ rolled in the fix
for libjpeg_turbo's GYP file in Chromium. That was rolled into WebRTC
in https://codereview.webrtc.org/1985423004/. That means our Android
x86 builds can start working again.
