Fix temperatures not showing (#101, #103)

Sometimes a temperature sensor file in `/sys/class/hwmon/hwmon*/temp*_*` will return 'ENETDOWN: Network is down' when being read for some reason, which gopsutil propogates up to gotop. gopsutil still returns a slice of valid temperatures when it errors, so we can render those instead of ignoring the return value.
