Break the @bazel_tools//tools/def_parser:def_parser cycle in the default case

This matches the setup used by the native rules: https://github.com/bazelbuild/bazel/blob/eb23cdb2e1813db3add8878dd28e0cd5f38513f9/tools/cpp/BUILD.tools#L56-L76

This is not a complete fix as noted in bazelbuild/bazel#27103 (comment) but at least preserves the old behavior.
