Robert,

because I still have build artifacts of chromium I had spend some time to
track and fix the issue with crash in developer tools when enable
perofmrance recording.

It was trivial: nobody implemented SystemPowerMonitor on BSD, and it just
crashed on NULL provider.

Tested in ungoogled-chromium, but the same patch propagated for chromium and
iridium and tested as make patch.

Ok?
