libxc: NetBSD: implement xc_evtchn_bind_unbound_port.
Doesn't actually appear to be used anywhere but is defined for other
OSes.
The NetBSD evtchn.h contains comments "Return allocated port" for
several ioctls which currently return the allocated port as a member
of the argument structure and not as the ioctl return value (I think
this is a cut and paste error).
