Add a new test to exercise the virtionet driver in GRUB as well as
some elements of the network stack. This uses Python3 on the host
to run a local HTTP server on the host / Qemu virtual interface
and GRUB will download a GRUB file over HTTP and the host and GRUB
calculated hashes are then compared.
