util/amdfwtool: Include the header with __packed definition

Checkpatch script recommends to use __packed instead of
__attribute__((packed)). Currently the build rule for amdfwtool does not
include the required header file with __packed definition. Update the
compiler flag to include the required header file.

BUG=None
TEST=Build amdfwtool.
