* Add initial bpftool tests and another libbpf test
And fix various bugs hit by the tests.
This PR only adds a couple of initial tests.
A future PR will add many more tests.
bpftool_tests.exe is meant to be run on a machine with the drivers
installed. A future PR will add it to the KM test runner in CI/CD.
