The verifier will parse "maps/*" sections, and is able to deal with
maps sections with various record sizes. This PR updates bpf2c to
use the same algorithm. In the future it would be good to refactor
the verifier so the same code can be used.

* 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.
