udev 171: add recipe with DP = -1

This is meant for people to test before making it the default. The goal is to
get rid of as many udev rules as possible to speed up boot time

Some numbers of udev-trigger running on beagleboard/angstrom:

udev with no accept4() syscall in libc: 180s

udev 168 with default rules: 	12s
udev 171 with default rules:	8s
udev 171 with minimal rules		0.8s

These times vary with the number of devices attached, SD card speed, etc.
