package/spice: fix libressl build

Fix the following build failure raised since bump of libressl to version
3.5.2 in commit 8b216927db:

red-stream.cpp: In function 'RedStreamSslStatus red_stream_ssl_accept(RedStream*)':
red-stream.cpp:526:22: error: invalid use of incomplete type 'SSL' {aka 'struct ssl_st'}
  526 |     stream->priv->ssl->s3->flags |= SSL3_FLAGS_NO_RENEGOTIATE_CIPHERS;
      |                      ^~

Subject: [PATCH] server: add SSL_OP_NO_RENEGOTIATION fallback path
With LibreSSL SSL_OP_NO_CLIENT_RENEGOTIATION is opaque which is not
compatible with the OpenSSL 1.0.2 and earlier code path in
red-stream.cpp while SSL_OP_NO_RENEGOTIATION is not yet defined for the
newer OpenSSL code path in reds.cpp.
So with OpenSSL 1.1.0 and later if SSL_OP_NO_RENEGOTIATION is undefined
and SSL_OP_NO_CLIENT_RENEGOTIATION is defined then define the former as
the latter. This will allow the build to succeed with LibreSSL 3.7.2 and
in the future when newer LibreSSL versions add SSL_OP_NO_RENEGOTIATION
that code path will then be used automatically.
