[OE-core] [PATCH] initramfs-framework/setup-live: also boot live image if root=/dev/ram0

[California Sullivan]

Our grub and syslinux bootloaders both define root=/dev/ram0 for live
images by default. Kernel docs show that root=/dev/ram0 is just a
sentinel value to mount the initrd as root, which we're already doing
in this path, so just check for a missing root= parameter OR
root=/dev/ram0.

NOTE: for the selftests to be fixed, the patch
"initramfs-framework/setup-live: remove superfluous break" needs to be
merged as well.
