mac: Update knowledge of CFAllocator internals for 10.12

For each new major OS version, we need to poke at the internals of
CFAllocator to enable the out-of-memory killer for the default
CFAllocator implementations.

This update is for macOS 10.12 ("Sierra"), whose CFAllocator internals
are unchanged from 10.11 (and from 10.9, and in fact from 10.7). It also
updates the base::mac::IsOS*() family of functions for this new OS
version.
