Work around inability to build Linux CGO on Mac

The combination of CGO and GOOS=Linux breaks compilation on a Mac, which has the result of breaking Vim's compilation error checking. We've worked around this by adding a non-CGO implementation of our single CGO package, which will be used when CGO_ENABLED=0. We're adding that env var setting to our Vim alias in the garden-dotfiles repo. [finishes #139469133] Signed-off-by: Gareth Clay <[email protected]>
