> Mac: Do not ask to handle power events in processes with no PowerManager.
> 
> Otherwise Chrome causes a 30-second delay trying to put a Mac to sleep.
> 
> Only the main browser process, and nacl processes, create a
> PowerMonitorDeviceSource. However, renderers and other processes still
> call the static function PowerMonitorDeviceSource::AllocateSystemIOPorts.
> This results in the process asking to receive power change
> notifications, but not hooking up a function to acknowledge them. This
> results in 30-second timeouts while trying to sleep a Mac.
> 
> This change removes plugin, renderer, utility and worker processes from
> the list of process types that register to receive power change events
> from OS X.

> TEST=Put a Mac to sleep with Chrome running. After waking, run `pmset -g
