[BusyBox] init RESTART action does work in 1.00-pre2

[Yang Xiaopeng]

Hi,

In busybox 1.00-pre2, I found a new line

	signal(SIGHUP, reload_signal);

added in init.c, cause init just reload inittab and run RESPAWN action 
when receive SIGHUP signal, not exec RESTART action, and the restart 
stuff in inittab seems to be ignored. But someone(like me) may change 
the restart stuff to other program than /sbin/init, and it doesn't work 
now.

I don't know what the author think about this, but I really hope it can 
work as before.
