Enable backward compatibility tests on Mac

[cwperks]

Description

Whenever I run ./gradlew localDistro I see the following banner as the first output:

========================= WARNING =========================
         Backwards compatibility tests are disabled!
See https://github.com/opensearch-project/OpenSearch/issues/4173
===========================================================

This banner refers to a now closed github issue: #4173

I am able to run BWC tests from my mac. Example command: ./gradlew qa:full-cluster-restart:'v3.1.0#bwcTest'
