* lib/stat-time.h: (get_stat_birthtime): Check for zero-valued
birthtime on all systems, not just those which use
st_birthtimensec rather than st_birthtim. Putting zero in
st_bithtim.tv_sec is how (for example) FreeBSD/x86 6.1
indicates that the birth time is not available for files on
an NFS mount.
