MacOS wheel building is flaky

[yngve-sk]

Edit: Might be related (maybe also resolved) by explicitly passing DYLD_LIBRARY_PATH when calling delocate (ref: pypa/cibuildwheel#816)

The MacOS Carolina wheel building often fails due to delocate not finding packages, shows up with empty search path, even though it is correctly set. Solution for now is to just re-run until success, which is fine because we only need to build each wheel once and upload to pypi. This is a bit fragile and should be fixed in the long term.

Steps to reproduce:
Go to actions, and run the workflow 🏎️ Make & Test Wheels 🏎️ (until it fails) with an error like:

Note the empty search paths, and the otool output is also given above, which indicates that the wheel does have things set to the rpath
