Look for visible vols for a user under /mnt/user/<userId>/package/.

Currently, we pass down visisble volumes for a user to zygote so that
it can set up appropriate bind mounts after forking. This method has
atleast a couple of race conditions, so instead make zygote just
look under /mnt/user/<userId>/package for volumes that need to be
handled for a particular user.
