build: fix infinite loop in build-release-packages task

[crisbeto]

Fixes an infinite loop in the build-release-packages task because an import from inside a package was referring to itself.

I see that you just added the pr: merge ready label, but the following checks are still failing:
     status "ci/circleci: build_release_packages" is failing
     status "ci/circleci: api_golden_checks" is pending
     status "ci/circleci: bazel_build" is pending
     status "ci/circleci: e2e_tests" is pending
     status "ci/circleci: ivy_test" is pending
     status "ci/circleci: lint" is pending
     status "ci/circleci: tests_browserstack" is pending
     status "ci/circleci: tests_local_browsers" is pending
     status "ci/circleci: tests_saucelabs" is pending

If you want your PR to be merged, it has to pass all the CI checks.

If you can't get the PR to a green state due to flakes or broken master, please try rebasing to master and/or restarting the CI job. If that fails and you believe that the issue is not due to your change, please contact the caretaker and ask for help.

😱 I think this won't happen with Bazel.
