net/filter-rewriter.c: Make filter-rewriter support vnet_hdr_len
We add the vnet_hdr_support option for filter-rewriter, default is disabled.
If you use virtio-net-pci or other driver needs vnet_hdr, please enable it.
You can use it for example:
-object filter-rewriter,id=rew0,netdev=hn0,queue=all,vnet_hdr_support
We get the vnet_hdr_len from NetClientState that make us
parse net packet correctly.
