enable compilation of native_mixed on macos

Issue #349 requires a native_mixed for macOS.
native_mixed is working for libzim so we whitelist it.

On the release CI, we fix the macos dylib rpath so it doesn't include the
full build-install step path which is probematic for a distributed file.

We build native_mixed for OSX in both CI and release mode
