This is not specific to your setup.  Emacs deliberately includes in
Info-directory-list both the source and the installation directories.
This is explained in the doc string.

This is also not unimportant.  info.el goes to great lengths to
streamline the top-level Info directory, so that code better be right,
or we should simply remove it.
