Move HsDirectoryConfig.h to root directory

This is avoids the need to create the "include" directory whenever
autoreconf is initially run from a fresh repo, as once HsDirectory.h is
removed later on there will no longer be an "include" directory in the
Git repo.  (We could of course create a dummy file to keep the "include"
directory, but that adds unnecessary clutter to the Git tree.)
