description:
SSL: reasonable version for LibreSSL adjusted.

OPENSSL_VERSION_NUMBER is now redefined to 0x1010000fL for LibreSSL 3.5.0
and above.  Building with older LibreSSL versions, such as 2.8.0, may now
produce warnings (see cab37803ebb3) and may require appropriate compiler
options to suppress them.

Notably, this allows to start using SSL_get0_verified_chain() appeared
in OpenSSL 1.1.0 and LibreSSL 3.5.0, without additional macro tests.

Prodded by Ilya Shipitsin.
