tls/openssl: add LibreSSL support

Browse Source 
OpenSSL and LibreSSL versions are incompatible. Moreover, LibreSSL
always define OPENSSL_VERSION_NUMBER as 0x20000000L. Instead of checking
for LibreSSL everywhere explicitly, redefine OPENSSL_VERSION_NUMBER.

See similar issues with nginx project: https://trac.nginx.org/nginx/ticket/1605
