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)
