Reading brightness value for backlight device can fail intermittently (particularly when using ddcci-driver-linux). Handle this more gracefully rather than crashing

This actually updates the value (to 0) when getting the sysattr fails, so the percentage in the bar changes to 0 for a second until the next update. seems undesirable; should just avoid doing the update instead. |
Avoids the brightness percentage resetting to 0 on intermittent failures
