* The current issue is that unsafe headers is a target build on demand
when the `allow_ddk_unsafe_headers` flag is set, for this reason this
test uses a transition to force that flag to be set.
* This introduces a new Bazel sub-package bazel/test which could be used
later for more tests if needed.
Tested: tools/bazel test //common/bazel/test
