[OE-core] [PATCH 2/4] initramfs-module-setup-live: add realroot

[Hongxu Jia]

The setup-live module of initramfs-framework is introduced to integrate
the functionality of init-live.sh, but it missed to create /media/realroot

Refer init-live.sh, add scriptlet named `realroot' after scriptlet `union-fs'
