[PATCH] util: remove compile time tests for IFF_VNET_HDR/IFF_MULTI_QUEUE

[Daniel P. Berrangé <berrange@xxxxxxxxxx>]

The former has been present since

  commit f43798c27684ab925adde7d8acc34c78c6e50df8
  Author: Rusty Russell <rusty@xxxxxxxxxxxxxxx>
  Date:   Thu Jul 3 03:48:02 2008 -0700

    tun: Allow GSO using virtio_net_hdr

and the latter since

  commit bbb009941efaece3898910a862f6d23aa55d6ba8
  Author: Jason Wang <jasowang@xxxxxxxxxx>
  Date:   Wed Oct 31 19:45:59 2012 +0000

    tuntap: introduce multiqueue flags

these are old enough that they can be assumed present in all Linux
platforms we support. The tap device creation code changed is specific
to Linux, with a separate impl for non-Linux platforms.
