Subject: [PATCH] C API: Only use foreign-types on macOS
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Its only use is for CoreAnimationLayerRef::from_ptr() in
PFMetalDeviceCreate, so this fixes a warning on other platforms.

The last time I tried to fix this warning I didn’t notice that it was
actually used, and thus 2d2bc14e5cb597bc9c8f602d28c4a16902fd1938 broke
the macOS build in #257.
