config: add libudev input-hotplug backend

Add a backend using libudev for input hotplug, and disable the hal and
dbus backends if this one is enabled.

XKB configuration happens using xkb{rules,model,layout,variant,options}
properties (case-insensitive) on the device.  We fill in InputAttributes
to allow configuration through InputClass in Xorg.

Requires udev 148 for the input_id helper and ID_INPUT* properties.
