file: Teach GLOB to list directories optionally 

GLOB lists directories by default and GLOB_RECURSE does not.
LIST_DIRECTORIES enables user to control the behavior explicitly for
consistently for both GLOB and GLOB_RECURSE.

:policy:`CMP0009` is not set to ``NEW``.
By default ``GLOB_RECURSE`` omits directories from result list - setting
``LIST_DIRECTORIES`` to true adds directories to result list.
If ``FOLLOW_SYMLINKS`` is given or policy :policy:`CMP0009` is not set to
``OLD`` then ``LIST_DIRECTORIES`` treats symlinks as directories.
Examples of recursive globbing include::
/dir/*.py - match all python files in /dir and subdirectories
