up-device-battery: Recover the charging threshold settings when restarting

Browse source 
The configuration file holds the enable status of the battery charging
threshold for individual batteries. If it is enabled, upower will recover
the settings when upower starts up. If the configuration file is not
present, the battery charging threshold is disabled by default.
