Avoid spurious directory metedata split brain
When directory content is modified, [mc]time is updated. On
Linux, the filesystem does it, while at least on NetBSD, the
kernel file-system independant code does it. This means that
when entries are added while bricks are down, the kernel sends
a SETATTR [mc]time which will cause metadata split brain for
the directory. In this case, clear the split brain by finding
the source with the most recent modification date.
