Re-ran the conversion of all DH parameters

Re-ran the conversion of all DH parameters

I get different results now to those I got before.

Now, using gen_pkcs3 linked against OpenSSL 1.1.1f-1ubuntu2 on Focal Fossa, I
get the results below.  The ffdhe2048 value now matches that at
<https://ssl-config.mozilla.org/ffdhe2048.txt>.

I ran the same code yesterday for just the ffdhe2048 item and got code which
seemed to me then to match what was already in the C file.  Something hinky is
going on, perhaps with my sanity.

(the commit IDs changee because of heavy rebasing (heiko))
