[BusyBox] bug#1003: Fix for #1003

[Matt Kraai]

Howdy,

The function halt_signal in busybox/init.c is supposed to handle both
poweroff and halt.  It does this by determining whether it was notified
by SIGUSR1 (for halt) or SIGUSR2 (for poweroff).  However, when setting
up the signal handlers, it appears that SIGUSR2 is bound to
reboot_signal, so that the code to handle poweroff is never reached.
The attached patch changes it to use the correct signal handler.
