add compatibility between icecube800bc and celesticabmc

Summary:
Recently we change the image name of `icecube800bc` BMC to `celesticabmc`. This means newer BMC image of `icecube800bc` use `celesticabmc` name instead

However, there are some `icecube800bc` devices that are already delivered and we would like to have those devices to be able to be flashed with newer `celesticabmc` image

This diff introduce compatibility check to prevent `flashy` tool from raising issue if it encounter this case (`icecube800bc` device is flashed with `celesticabmc` BMC image)

Test Plan:
# unit test
