Also, rename get_battery_identifier() to siphash24_compress_device_sysattr(). This also makes any errors in sd_id128_get_machine() or id128_get_product() ignored. For the machine ID, the failure should not be significant unless the file stored in the discharge level is reused by another system, which is quite unusual. For the product ID, if the firmware provides useless ID (all zero or all 0xFF), then loading/storing the discharge rate becomes completely broken, that should be avoided. Note, now sysattrs are used instead of properties in uevent files, but both provide the same information, hence no functionality should be changed.
