[PATCH] init: Set the RUNLEVEL environment

Busybox's init application does not use the runlevel argument, except
for the special case of single-user mode. This patch passes the
runlevel argument on to the children processes in the environment
variable RUNLEVEL so that they may do something with it. For example,
I have an /etc/rc file that simply calls /etc/rc$RUNLEVEL. This
behaviour matches that of the standard Linux System-V-like init
application. Please apply.
Cheers,
Shaun
