examples/vdpa: enable vIOMMU

When we run dpdk vdpa in the nested virtual machine vm-L1 and ping
test in vm-L2, the ping is not good. The reason for troubleshooting is
that the virtio net in vm-L2 sends control information to the vring,
and the qemu back-end device in vm-L1 cannot obtain correct data
from the vring. This problem is related to the opening of the vIOMMU.

This patch add flag RTE_VHOST_USER_IOMMU_SUPPORT to use vhost vIOMMU,
VIRTIO_F_IOMMU_PLATFORM feature will be negotiated successfully if
virtio IOMMU is used in a nested virtualization environment.

The configuration is as follows:
The host starts iommu, and the kernel parameter is added with
'intel_iommu=on iommu=pt'.
VM-L1's xml add viommu and virtio device adds iommu='on' ats='on'.
VM-L2's xml enables viommu, and adds parameters
'intel_iommu=on iommu=pt' to kernel.

Then the ping test in vm-L2 is OK.
