Revert "HACK: Lol libwebrtc"

This was fixed over two years ago in
https://webrtc-review.googlesource.com/c/src/+/305120 so hope it has
permeated through all CEF applications using screen casting.

reported in https://issues.webrtc.org/issues/42225490 and
https://bugzilla.mozilla.org/show_bug.cgi?id=1832770

This reverts commit 206b0aa.
