or-tools: add darwin support

[sdedovic]

Description of changes

Add support for or-tools on Mac. Build was borked because of @rpath issues in the generated dynlib and binaries used for testing (checkPhase a la ctest). This works on my machine so sharing the changes with all.

Some related discussion:

• cmake MACOSX_RPATH
• Get rid of most @rpath nonsense on Darwin #30150
• LLVM mailing list on RPATH

This also seems to me the lesser of two evils. fixdarwindylibnames exists but presents two problems, making it insufficient.

1. the script runs after the checkPhase, so I need to run it as the postBuildHook as ctest uses linked objects and fails to pass.
2. the script only patches dylib files. This project creates a large amount of executables that do not get patched and are used by ctest. Again failing the checkPhase.

Open to thoughts, I'm using it now and it functions well enough.

Build passes on macOS 13.1, both aarch64-darwin and x86_64-darwin (via Rosetta).

@wegank not for me, still getting the same results as above.

@ofborg build or-tools or-tools.passthru.tests

[sdedovic]

@Atemu @wegank please see my latest commit

The checkPhase was an issue because it could pip install from PyPi a newer version instead of the local one. I believe this is fixed in or-tools 9.5 or 9.6, so I have backported the patch. This has successfully built on my M1 mac.
