net/filter-mirror.c: Add new option to enable vnet support for filter-redirector

Browse Source 
We add the vnet_hdr_support option for filter-redirector, default is disabled.
If you use virtio-net-pci net driver or other driver needs vnet_hdr, please enable it.
Because colo-compare or other modules needs the vnet_hdr_len to parse
packet, we add this new option send the len to others.
You can use it for example:
-object filter-redirector,id=r0,netdev=hn0,queue=tx,outdev=red0,vnet_hdr_support
