Change the scripting inside the shipped/extra certs C code
generation to not write the file when there are any failures.
That way, if the build aborts due to failures, we don't get
into a situation where a dummy file has been created and the
next build succeeds, but not with the desired output.
Fixes: 90a53e4432 ("cfg80211: implement regdb signature checking")
