posix: use nanosecond accuracy when available
Programs that set mtime, such as `rsync -a`, don't work correctly on GlusterFS, because it sets the nanoseconds to 000. This creates problems for incremental backups, where files get accidentally copied again and again. For example, consider `myfile` on an ext4 system, being copied to a GlusterFS volume, with `rsync -a` and then `cp -u` in turn. You'd expect that after the first `rsync -a`, `cp -u` agrees that the file need not be copied.
