bazel: Fix bazel query and provide a default java toolchain

These are fixes for problems I ran into with:
- `bazel test //example:cpp-test`
This needed `build --host_javabase='@local_jdk//:jdk'`

- `bazel query 'deps(//example:cpp-test)'`
This needed the same flags as `build`.

Is it contentious to (partially?) configure the default java toolchain? I don't see it as much different than providing the bazel server's java.
It would continue to be configurable/overridable by overriding the flags.

And a random notes from this escapade, but https://github.com/bazelbuild/bazel/blob/master/WORKSPACE#L144-L308 looks a little different from https://github.com/NixOS/nixpkgs/blob/master/pkgs/development/tools/build-managers/bazel/bazel_3/src-deps.json so one of them is probably wrong :)
