    avahi-ui: use PACKAGECONFIG for gtk features
    
    The commit "054ea20 avahi-ui: Build with Gtk+3"
    enabled gtk3 and disabled gtk2, which causes failure on
    some package depends on gtk2, like gnome-disk-utility
    in meta-openembedded/meta-gnome:
    
    | checking for GTK2... yes
    | checking for AVAHI_UI... no
    | configure: error: Package requirements (avahi-ui >= 0.6.25) were not met:
    |
    | No package 'avahi-ui' found
    
    The gtk2 and gtk3 feature for avahi-ui is not exclusive, so change
    to use PACKAGECONFIG for them so we can easily enable/disable one
    of them or both of them as needed.
