[gnome-initial-setup/wjt/gweather-4: 6/9] timezone: Build against gweather-4.0

[Will Thompson <wjt src gnome org>]

commit 0c37347e20f1a995c9b6fb772ee377dcc35bcdb5

    timezone: Build against gweather-4.0
    
    GWeather 4.0 removes GWeatherLocationEntry and, as a result, its
    dependency on any version of GTK.
    
    For now we just replace this widget with a plain GtkEntry. A subsequent
    commit will re-introduce an imported & adjusted copy of GWeatherLocationEntry.
