initrdscripts: add install scripts with a second rootfs

These are meant to be used by a master image, for a simple
initial setup.
The install scripts are similar to the default ones, but:
- custom partitioning, replaces the swap partiton with a second root filesystem
- adds labels to the partitions
- preconfigures a boot loader entry for the second rootfs

Part of [YOCTO #5614]
