[openssl-project] Kudos to Matt on the genpkey doc rewrite

[Viktor Dukhovni]

I'd like to thank Matt for going above and beyond the immediate issue raised (documenting the EdDSA algorithm options) and thoroughly updating the genpkey(1) manpage, reviewing the code and fixing bugs, etc.

This is the kind of thoroughness that it takes to pay down past technical debt and prove that the project is worthy of the recognition awarded through the Levchin prize.  Thanks Matt.  Great work!
