qtlinks: almost dump Qt4, unify creation of config & plugin links

Note, bee throws a warning ...

 WARNING: system and image files named '/usr/local/lib/plugins' differ
          image : directory
          system: symbolic link to /usr/local/qt5/lib/plugins

What is correct, so instead of update it is:

 #> bee remove qtlinks-1.0.1-5.x86_64
 #> bee install qtlinks-1.0.2

qtlinks.be0
