i440fx-test: generate temporary firmware blob
The blob is 64K in size and contains 0x00..0xFF repeatedly. The client code added to main() wouldn't make much sense in the long term. It helps with debugging and it silences gcc about create_blob_file() being unused, and we'll replace it in the next patch anyway.
