GnuTLS: Get rid of warnings about deprecated typedef names

'_t' suffix for gnutls_session and gnutls_transport_ptr was added in
GnuTLS 1.1.11 over ten years ago and the more recent versions of GnuTLS
have started forcing compiler warnings from the old names. Move to the
new names and don't bother about backwards compatibility with older
versions taken into account how long ago this change happened in GnuTLS.
