The license was discussed in the original code review in
https://codereview.chromium.org/2761163003#msg15, but it seems that
changing the license was chosen instead. There no longer appears to be
an issue with presubmits when a compatible license is used.

Only tools/perf/page_sets/update_webrtc_cases is manually edited in this
CL. Other changes were generated by this script.

`./tools/perf/run_benchmark run webrtc --browser=system` passes locally
on Mac.
