src: set SSL_OP_ALLOW_CLIENT_RENEGOTIATION

This commit sets SSL_OP_ALLOW_CLIENT_RENEGOTIATION for OpenSSL 3.0 as
this option is not set by default as it was in  previous versions.

Without this option set there are a few tests that fail when linked
against OpenSSl 3.0.0-alpha-17, for example
test-https-client-renegotiation-limit.js.

I'm not sure we should be setting this for OpenSSL 3.0 or not, but
I'll take a closer look at the implications but if nothing else this
would allow for us to update to alpha-17 in the mean time.
