Subject: Bug 1775143 - pt2 - apply reconciling patch to match previous import
 r=ng

tl;dr We commit extra changes when we vendored this for the v86 import,
so we need to do the equivalent here again.  For more info see:
https://wiki.mozilla.org/Media/WebRTC/libwebrtc_Update_Process/automation_plan#verify_current_vendoring_scripts_cmd-line_params
and
https://wiki.mozilla.org/File:Vendor-build-fixup.patch.zip

(skip-generation)

Depends on D149807
