We add the vnet_hdr_support option for filter-mirror, default is disable.
If you use virtio-net-pci net driver, please enable it.
You can use it for example:
-object filter-mirror,id=m0,netdev=hn0,queue=tx,outdev=mirror0,vnet_hdr_support
If have vnet_hdr_support flag, we will change the send packe
If user use -device virtio-net-pci, virtio-net driver will add a header
to raw net packet that colo-proxy can't handle it. COLO-proxy just
focus on the packet payload, so we skip the virtio-net header to compare
the sent packet that primary guest's to secondary guest's.

Because colo-compare or other modules needs the vnet_hdr_len to parse

You can use it for example:

It was only used by XBZRLE anyways.

If you use virtio-net-pci or other driver needs vnet_hdr, please enable it.
You can use it for example:
-object
colo-compare,id=comp0,primary_in=compare0-0,secondary_in=compare1,outdev=compare_out0,vnet_hdr_support

Change it to be consistent with everything else.
