Fix the from-source feature of openvino-sys

The CMake configuration options, targets, etc. have changed with
OpenVINO 2022.1.0. This change fixes the feature in `openvino-sys` that
allows a user to bind the crate to a locally-built version of OpenVINO.
The Git submodule has been updated to the `releases/2022/1` branch,
which causes some small changes to the genrated bindings files.

The `from-source` feature now has a significant amount of logic, which
prompts me to wonder whether it is worth the effort. Also, this change
disables the `detect_inception` test (which works in other kinds of
builds) since it fails with a mysterious general error.
