Currently the VM is configured with QEMU's i440FX machine type which has no
PCIe support (among other restrictions). This changed the Vagrantfile so that
the it boots a q35 machine instead.

The commit a043363 introduced improvements to the vfio
functional test which now requires the driverctl tool. The
driverctl package is installed in the host via .ci/vfio_jenkins_job_build.sh,
but that script is never called by the .ci/setup.sh; as a result, the
package isn't installed when I run the Vagrant-based job locally.

This commit adds the driverctl (also pciutils) to the list of packages
installed in the host Fedora and Ubuntu.

The Vagrantfile was changed so that the VM will have IOMMU enabled
and an additional virtio-net device in case of the VFIO job.

Additional Kernel command-line arguments are required to enable IOMMU,
therefore GRUB is reconfigured and the VM should reboot.

The vagrant configuration sometimes can get into inconsistent state. For
instance, the domain on libvirt was created by the framework that thinks
the box is not initialized yet. Or eventually the developer wants to
simply wipe out all vagrant files and created resources from his/her
workstation.

In this commit it was introduced the vagrant-cleaner.sh script which
aims on help developers to clean up the vagrant stuffs.

Added on README.md a table with the combinations of tested host
versus guest so developers are aware of what is (or not) expected
to work.

By default Vagrant creates the domain in libvirt prefixed with
the project's directory name, in our case it is "tests-". Let's
use meaningful name instead.

Below is shown the new domain names in libvirt.

$ virsh list --all
 Id   Name                          State
---------------------------------------------
 1    kata_containers_test-ubuntu   running
 4    kata_containers_test-fedora   running

The grubby package is already installed in the pulled VM image.

The installation of packages in the generic/fedora32 box is way faster
than the currently used fedora/32-cloud-base. In my laptop it can save
approximately 30min of the time to `vagrant up fedora`. So in this
commit I am switching the box used.
