SSL: disabled renegotiation checks with SSL_OP_NO_RENEGOTIATION.

Following 7319:dcab86115261, as long as SSL_OP_NO_RENEGOTIATION is
defined, it is OpenSSL library responsibility to prevent renegotiation,
so the checks are meaningless.

Additionally, with TLSv1.3 OpenSSL tends to report SSL_CB_HANDSHAKE_START
at various unexpected moments - notably, on KeyUpdate messages and
when sending tickets.  This change prevents unexpected connection
close on KeyUpdate messages and when finishing handshake with upcoming
early data changes.
