tls_tstream: increase the buffer size

The problem is that with certain version of gnutls are not working
properly if the server is sending in different packet things like (at
least)

* Certificate
* Server Key exchange
* Client certificate

Somehow it really expect this to be done in one packet as some
structures used _gnutls_send_handshake are reinitialized at every
packet exchange and intermediate steps didn't expect it
