Compile openssl-dynamic against libssl-1.1

The dynamically linked OpenSSL netty-tcnative doesn't work on Alpine Linux 3.9 and newer.

Linux netty-tcnative artifacts work fine for (our Hazelcast) Docker images based on Alpine Linux 3.8.

The problem is, Alpine 3.9 and newer updated the libssl in the system and only version 1.1 is available. The netty-tcnative doesn't work with this libssl version.

We are considering workaround (in hazelcast/hazelcast-docker#126) which would use openssl (and libssl) from Alpine 3.8, but it would be great to have it resolved in the openssl-dynamic module in the netty-tcnative. E.g. have both versions compiled and provide them either in different artifacts or use some kind of fallback.

Start with the openssl-dynamic module and reproduce the failure in the Alpine 3.11 Docker example using ldd on libnetty_tcnative.so. Compare its OpenSSL 1.0 dependencies with the available libssl.so.1.1, then determine how separate artifacts or fallback loading should be validated. Done means the dynamic artifact works with Alpine 3.9 and newer without breaking Alpine 3.8 compatibility.
