From: Chen Qi <Qi.Chen@windriver.com>

Add 'debugshell' as a default kernel option for ramfs booting.

If rootfs.img cannot be found under /media, init-live.sh loops
forever without showing any information. Silently looping forever
and blocking users is inappropriate.

Now that the 'debugshell' feature has been implemented in init-live.sh,
It's reasonable to add it to the kernel option when booting a ramfs-based
image. In this way, the system doesn't loop forever and instead drops
to a shell after a default timeout (30 seconds).
