misc: Bulk upgrade dependencies

In particular update for the vmm-sys-util upgrade and all the other
dependent packages. This requires an updated forked version of
kvm-bindings (due to updated vfio-ioctls) but allowed the removal of our
forked version of kvm-ioctls.

The changes to the API from kvm-ioctls and vmm-sys-util required some
other minor changes to the code.
