David Matlack d1a17495bb vfio: selftests: Add iommufd_compat_type1{,v2} modes
Add new IOMMU modes for using iommufd in compatibility mode with
VFIO_TYPE1_IOMMU and VFIO_TYPE1v2_IOMMU.

In these modes, VFIO selftests will open /dev/iommu and treats it as a
container FD (as if it had opened /dev/vfio/vfio) and the kernel
translates the container ioctls to iommufd calls transparently.
