BUILD: fix compilation for OpenSSL-3.0.0-alpha17
Some changes in the OpenSSL syntax API broke this syntax:
#if SSL_OP_NO_TLSv1_3
OpenSSL made this change which broke our usage in commit f04bb0bce490de847ed0482b8ec9eabedd173852:
-# define SSL_OP_NO_TLSv1_3 (uint64_t)0x20000000
+#define SSL_OP_BIT(n) ((uint64_t)1 << (uint64_t)n)
+# define SSL_OP_NO_TLSv1_3 SSL_OP_BIT(29)
Which can't be evaluated by the preprocessor anymore.
This patch replace the test by an openssl version test.
This fix part of #1276 issue.
