Subject: Convert go_generics tests to starlark.

For some reason these tests were broken when run via the bazel docker
container. The mechanism used was a bit crazy (self-extracting bundle),
so convert them to use straight-forward starlark rules. This has the
added advantaged that they are now independent tests.
