[OE-core] [PATCH 1/1] initramfs-live-boot: Make sure we kill udev before switching root when live booting

[Alejandro Hernandez]

When live booting, we need to make sure the running udev processes are killed
to avoid unexepected behavior, we do this just before switching root,
once we do, a new udev process will be spawned from init and will take care
of whatever work was still missing

[YOCTO #9520]
