Translate address family in SlNetIfNDK

The translation of the family attribute of the socket address struct (from NDK -> SlNetSock and vice versa) in some APIs is missing: SlNetIfNDK_recvFrom * The caller can optionally pass a sock addr struct that should be filled in by the stack with the peer's info * The NDK fills in this struct within NDK_recvfrom with NDK value for family * But, the struct should have the SlNetSock value of family when the API returns SlNetIfNDK_sendTo SlNetIfNDK_connect * The caller passes a sock addr struct that contain's the peer's info t * The caller sets sa_family to an SlNetSock value and it is currently passed directly to the underlying NDK API as such * This should be translated to an NDK value before passing the struct to the NDK API.
