mmap: add define for MAP_FILE

This is unused but defined in Darwin, BSD, and Linux. It allows developers to feel good about specifying that they want to map a file (which is the default behavior anyway). The value is 0, so specifying this flag does not have any effect. This allows to more easily compile code that uses the flag.
