The addition of local_repository in cc4b9c0#diff-6136fc12446089c3db7360e923203dd114b6a1466252e71667c6791c20fe6bdc appears to break "bazel fetch" when using rules_pkg as a Bazel module:

My MODULE.bazel

bazel_dep(name = "rules_pkg", version = "1.1.0")

$ bazel fetch
ERROR: The repository's path is "tests/mappings/external_repo" (absolute: "/home/sdoessing/my-project/tests/mappings/external_repo") but it does not exist or is not a directory.

It seems like Bazel assumes local_repository is relative to my project's root, rather than the root of rules_pkg.

Since WORKSPACE is on the way out, maybe this could be fixed by converting tests/mappings/external_repo into a module and using local_path_override instead?
