Disable the background responsiveness timer when RunningBoard is used. We used
to only disable it on iOS because we only used RunningBoard on iOS. However,
now that we use RunningBoard on macOS too, we should disable it on this
platform too. Background processes now get a very low priority and eventually
get suspended. This would cause false reports of unresponsive processes.
