pacman: show groups once with -Sg

Only displays groups that haven't appeared yet..
Previously 'pacman -Sg' iterated over syncs, printed every group.

This change does not affect '-Sgg' which still orders by sync first.

To reproduce, on a current Arch Linux with [extra] and [community]:
$ pacman -Sg|sort|uniq -c|sort -n
[...]
      1 xorg-fonts
      2 vim-plugins
      2 xfce4-goodies
