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.

We want to be able to run 64-bit ARM kernels using a 32-bit version of
crosvm, to make it more consistent use a u64 to represent
GuestAddress.

This fakes out the underlying Net implementation with FakeNet to try
and get some of the code a little further along before it
explodes. Then, we test for known failures when running without a real
vhost file descriptors.
This allows us to pass without running as root as we would expect
running on Paladins.
This is also the final module that was failing at ToT.
Also adds vhost to the build_test test targets.

A large portion of the VhostNet implementation is common to all vhost
devices. Create a new Vhost trait that encapsulates this behavior and
split the network specific bits into a new Net type and implement the
Vhost trait for it.
BUG=chromium:708267
TEST=build and run with a VHOST_NET enabled kernel and see that
everything still works fine
