Link directly to awesome/ dir

The problem with the old docs was that the .config/ dir was overwritten by
the link.  There are, however, many more files and directories stored under
.config than just awesome/ thus the .config/awesome dir in these dotfiles
needs to be in the main directory and not in the .config subdir.  At least
now the docs are correct.
