ocaml: remove bogus /dev/xen/ev[en]tchn

Oxenstored should not try to create the evtchn device, as it:

    * creates the wrong name (/dev/xen/eventchn rather than evtchn)
    * uses a hard-coded minor number, even though this dynamically
      depends on what other misc devices are in the kernel

Remove all this code and just rely on the system to create the device.
