Build Darwin test binaries on OS X when KUBE_FASTBUILD is set

Without this, on OS X, test binaries would not be built for the local ARCH, and test scripts fail with an obscure error due to not being able to find the correct binary to run.

This makes the behavior on OS X more consistent with Linux.

Tested on OS X and Linux.
