patch 8.0.0612: pack dirs are added to 'runtimepath' too late

commit https://github.com/vim/vim/commit/ce876aaa9a250a5a0d0e34b3a2625e51cf9bf5bb

    patch 8.0.0612: pack dirs are added to 'runtimepath' too late

    Problem:    Package directories are added to 'runtimepath' only after loading
                non-package plugins.
    Solution:   Split off the code to add package directories to 'runtimepath'.
                (Ingo Karkat, closes #1680)
