Make list_active more robust

A couple of small changes to this function should make it more robust in
the long run:

1) We no longer filter the symlinks with find(1), instead combining
   filtering and substituting in sed(1)

2) We use the absolute path (as given by readlink -f) such that we can
   anchor the regular expression pattern to avoid unwanted substitution.

3) Instead of hard-coding paths we now use STOW_DIR (and STOW_DIR/.. for
   the target directory)

4) To avoid unnecessary complexity, we no longer let the user override
   STOW_DIR. This tool is supposed to be used with the canonical
   /etc/portage/stow location
