Mark toolchains extension as reproducible

Copybara Import from #187

Needed a manual import with a copybara fix (top-level targets for transformed repositories need special casing)

BEGIN_PUBLIC
Mark `toolchains` extension as reproducible (#187)

This avoids an unnecessary and verbose lockfile entry for rules_java users. Uses `bazel_skylib`'s `modules.as_extension` to automatically detect the availability of the `reproducible` feature.

Closes #187
