crypto: ccp - Fix some unfused tests

Some of the tests for unfused parts referenced a named member parameter,
but when the test suite was switched to call a python ctypes library they
weren't updated.  Adjust them to refer to the first argument of the
process_param() call and set the data type of the signature appropriately.
