Add /postinstall partition when using the A/B updater.
The new top level directory /postinstall is used by the A/B updater to mount the new partition and run a post-install program before rebooting into that new system. init.rc was extended to label this new directory since the initrd has no extended attributes. Bug: 27177071 TEST=`ls -laZ /` shows the /postinstall directory on edison-eng (cherry picked from commit bb968fb04db3ec5227e84571e1c6bfd265836085) Change-Id: Iff993135c7ce3a1a0f6450892ef7382da408fd5e
