init-live.sh: avoid duplicate mount points for the same filesystem
A live system had duplicate mount points for the same filesystem
in the output of 'mount' command. That was because we didn't handle
the temporary mounts properly before switch_root.
This patch fixes this problem by moving the mount points of some
filesystems to the corresponding directories in the real root filesystem.
