Subject: [PATCH] shutdown: recursively mark root as private before pivot

Because root is now recursively marked as shared on bootup, we need to
recursively mark root as private. This prevents a pivot_root failure on
shutdown:

  Cannot finalize remaining file systems and devices, giving up.
  pivot failed: Invalid argument
(cherry picked from commit 4bfa638d43c05e8db052cd55818765bb3575a405)
