If compiled with the macOS 10.14 SDK, MAP_JIT will be defined and passed as a flag to mmap to allocate memory for the dynarec, but passing this flag will cause mmap to fail if running on macOS 10.13 and below; on macOS check the OS version at runtime, set and cache the appropriate flags for mmap.

Fixes #47
