Antonio Murdaca	6a3cd56f2e	pkg: chrootarchive: chroot_linux: fix mount leak ... When pivot_root fails we need to unmount the bind mounted path we previously mounted in preparation for pivot_root.

Antonio Murdaca	0bc559ba8a	pkg: chrootarchive: chroot_linux: fix docker build ... The path we're trying to remove doesn't exist after a successful chroot+chdir because a / is only appended after pivot_root is successful and so we can't cleanup anymore with the old path. Also fix leaking .pivot_root dirs under /var/lib/docker/tmp/docker-builder* on error.

Brian Goff	d7e08dc088	Use pivot_root instead of chroot for chrootarchive ... This fixes one issue with Docker running under a grsec kernel, which denies chmod and mknod under chroot. Note, if pivot_root fails it will still fallback to chroot.
