Driver core: add CONFIG_UEVENT_HELPER_PATH
The kernel creates a process for every event that is send, even when
there is no binary it could execute. We are needlessly creating around
200-300 failing processes during early bootup, until we have the chance
to disable it from userspace.
This change allows us to disable /sbin/hotplug entirely, if you want to,
by setting UEVENT_HELPER_PATH="" in the kernel config.
