SSL: disabled renegotiation checks with LibreSSL. Similar to 7356:e3ba4026c02d, as long as SSL_OP_NO_CLIENT_RENEGOTIATION is defined, it is the library responsibility to prevent renegotiation. Additionally, this allows to raise LibreSSL version used to redefine OPENSSL_VERSION_NUMBER to 0x1010000fL, such that this won't result in attempts to dereference SSL objects made opaque in LibreSSL 3.4.0. Patch by Maxim Dounin.
