Fix IndicatorLED "Blinking" value

Blink is not a valid value for Redfish IndicatorLED.
Blinking is though. Changed. See:
https://redfish.dmtf.org/schemas/ComputerSystem.v1_6_0.json
http://redfish.dmtf.org/schemas/v1/Resource.json#/definitions/IndicatorLED

LED D-Bus interface has the value "Blink". Updated.

Tested: Limited.
