Fix / delete disabled tests

There are some 'disabled in oss' tests that we should fix or delete https://github.com/bazelbuild/rules_apple/search?q=disabled+in+oss&unscoped_q=disabled+in+oss

Start with the linked repository search for tests marked "disabled in oss". Review each matching test to determine whether it can be fixed or should be removed, then run the relevant tests to verify the resulting suite; the issue does not name specific files or test commands.
