It depends on what you want to do. A server isn't obliged to renegotiate
just because the client asked. I don't know why openssl s_client asked
for renegotiation in your example.

Now that I check it, it does support renegotiation. I cannot check the
issue soon, but you can check the debugging output of gnutls-serv
using -d 9 or so.
