[OE-core] [PATCH] initrdscripts: add $CMDLINE to init-live switch_root

[krzysztof.m.sywula at intel.com]

From: Krzysztof Sywula <krzysztof.m.sywula at intel.com>

init-live.sh: $CMDLINE variable should be provided to switch_root
to let user specify runlevel on grub command line.
Feeding with -c /dev/console as well as busybox switch_root enables that option.
