Driver-Core: disable /sbin/hotplug by default

Browse source 
No recent mainstream system uses the /sbin/hotplug fork-bomb any more.
Disable it by default to reflect how it is used these days.

help
Path to uevent helper program forked by the kernel for
every uevent.
Before the switch to the netlink-based uevent source, this was
used to hook hotplug scripts into kernel device events. It
usually pointed to a shell script at /sbin/hotplug.
This should not be used today, because usual systems create
many events at bootup or device discovery in a very short time
frame. One forked process per event can create so many processes
that it creates a high system load, or on smaller systems
it is known to create out-of-memory situations during bootup.
