sys/stat.h: Improve timespec compatibility with other BSDs

Browse Source 
OpenBSD and NetBSD provide macros to directly reference the underlying
struct timespec's tv_nsec member.  While FreeBSD has such macros for
tv_sec, the others are missing.  Add the following macros:

st->st_atimensec
st->st_mtimensec
st->st_ctimensec
st->st_birthtimensec

Adding these fields will provide programs which reference them better
portability to FreeBSD.  An example of such a program is makefs(8),
which has unused support for subseconds that it has inherited from
NetBSD.
