virtio: remove kernel virtio header dependencies

Type: refactor

tap, virtio and vhost use virtio/vhost header files from linux
kernel. Different features are supported on different kernel
versions, making it difficult to use those in VPP. This patch
removes virtio/vhost based header dependencies to local header
files.
