[PATCH] keep pnpbios usermod_helper away from hotplug_path[]

These days we use udev to manage all kernel events. /proc/sys/kernel/hotplug
will usually be disabled by an init-script. pnpnbios is not integrated with
the driver core and should stay away from the now disabled /sbin/hotplug.

Set the helper to /sbin/phpbios, even when there is probably no current
user of this faciliy. If it's needed, it should definitely get proper driver
core integration instead of forking binaries from the kernel.
