ls: fix time handling by augmenting time resolution

ls was using (old) UNIX spec (struct stat).st_[acm]time.
It now uses POSIX (struct stat).(struct timespec st_[acm]tim) which
gives time resolution in seconds and nanoseconds.
If two files have the same time in seconds, we extend the comparision to
nanoseconds.
