Title: open-scene-graph: fix patch for 10.6

The patch for CMakeLists.txt was crafted to avoid a missing OR.
However there are still problems with the nested if/elseif on 10.6
where there's a build error complaining about the conditional.

- Change the patch and restructure the conditional to be simple:
- if 10.8 then do something, endif.
- if 10.7 then do something, endif.
- if 10.6 then do something, endif.
- That removes all complex logic and nesting.

Fixes #16076
