Disable setting of the SONAME (enabled by [2a2419ef742]), as it's not clear whether blindly setting the SONAME, which now differs from its historical value, will cause more grief than it solves. Add a (disabled) experiment which permits setting (or not) the SONAME to the legacy or current values. This change is up for further change as experimentation proves whether we truly need/want the SONAME. See discussion in/around [forum:0c6fc6f46b2cb3|forum post 0c6fc6f46b2cb3].
