deskutils/fet: Update to 6.9.0/Add flavors qt5 and qt6

- qt6 as default flavor as recommended by upstream

- Remove ONLY_CL option: qt6 flavor needs only one package so the ONLY_CL
  option is useless in qt6 (the number of dependencies don't decrease).
  I suggest to remove it because (as I understand) qt5 will be outdated soon.
