Interim state update in regard to swtpm-tools, gnutls-bin and libopts25.
Discussing with Steve it seems that - for now - the best option seems to be:
- to keep the ssl/tls lib relation -both seem complex and needed for various reasons e.g.
  Steve: "a lot of low-level gnutls operations, I assume because there were no available 
          equivalents in libssl"
- but at the same time we seem to be able to cut the ties to gnutls-bin by
  replacing the calls to certtool (form gnutls-bin) to sometrhing openssl based, that seems 
  possible and is on Steve.
- This would eliminate the need for gnutls28 + autogen MIRs

I'll update my post with the re-review content adapted to this outcome
