After 9e79ea1da719, it no longer makes sense for crashpad_util_test_lib to “hide” in util/util_test.gyp. All of util/test is moved to its own top-level directory, test, which all other test code is allowed to depend on. test, too, is allowed to depend on all other non-test code. In a future change, when crashpad_util_test_lib gains a dependency on crashpad_client, it won’t look so weird for something in util (even though it’s in util/test) to depend on something in client, because the thing that needs to depend on client will live in test, not util.
