In SERVER-41970 we refactored how RPATH worked. During review it was decided that the addition of ../Frameworks to the RPATH was no longer required, however, that was not the case, and it broke the macOS builder.

We can either restore the hard-coded use of ../Frameworks, or perhaps inject it on the command line for just that builder. We could also decide to not use framework installation for the C driver, which might be simpler. Nothing actually consumes the embedded library as a framework right now.
