[sr-dev] [kamailio/kamailio] http_client/http_async_client crash at startup if used with tls and openssl 1.1 (Issue #2912)

[kdanderso]

### Description

When attempting to use either http_client or http_async_client with tls support enabled and openssl version 1.1.x, Kamailio crashes at startup.

If openssl is reverted to version 1.0.2r as described in #1860, the issue does not occur.

#### Reproduction

On a system using openssl version 1.1.x (e.g. 1.1.1l) start Kamailio 5.5.2 with this config file for http_client failure:

To test http_async_client, load pv.so and http_async_client.so instead of http_client.so.
