Modify sharenfs=on default behavior

While it may sometimes be convenient to export an NFS filesystem with
no_root_squash it should not be the default behavior.  Align the
default behavior with the Linux NFS server defaults.  To restore
the previous behavior use 'zfs set sharenfs="no_root_squash,..."'.
