warp7: select uuid partition based on rootpart
Assigning the UUID discovery path to a tweakable environment variable means
that later steps in the boot process - particularly a boot script can
change the target root partition of a particular Linux boot.
Retargeting the rootfs is an important feature when doing ping/pong
upgrades allowing a boot script to select ping or pong as necessary without
reprogramming the bootloader.
