fix recursive rebooting by disabling signals

Doing

    while [ 1 ] ; do reboot ; done

with busybox 1.15.2 init causes recursive calls to the shutdown scripts. This patch fixes the issue by disabling the signals at the first invocation of the handler.

(The example above is a bit constructed, but it can also happen in some real-world scenarios).
