update Debian support

- LOS::userHasShutdownAccess -- proper return [fix compiler warning]
- LOS::systemCanSuspend -- proper return [fix compiler warning]
- LOS::CPUTemperatures -- get cpu temp [XXX untested as my FX-8350 doesn't talk to me]
- LOS::CPUUsagePercent -- get cpu usage
- LOS::MemoryUsagePercent -- get memory usage
