We recently added a new folder for common bazel utilities
to `dev-infra`. The `ng_rollup_bundle` rule relies on an
utility that is provided by this `bazel/` folder.
Unfortunately though it looks like this folder is currently
not included in the NPM package, so that the `ng_rollup_bundle`
rule does not work as expected. This commit fixes that by
including the bazel utilities in the NPM package.
