Introduce bazel / gazelle (#25)

* Add WORKSPACE & BUILD.bazel

* Add bazel symlinks to gitignore

* makefile: regenerate bazel as part of depend target

We also delete and regenerate any vendored BUILD BUILD.bazel files,
many go libraries ship BUILD / BUILD.bazel files that aren't valid
under vendoring.

* gazelle: generate BUILD.bazel files
