hw/virtio/vhost: Add simple tests backed by fakes

This slightly advances the use of fakes to test higher level
application logic. The fakes are rudimentary at this point, but I
wanted to get feedback on the addition of generics in order to
facilitate swaping concrete implementations out with fakes in higher
level code.

TEST=./build_test and
