    meson: Depend on GLib >= 2.68
    
    fedefd99fd2c6f6a2515dddaf72b43d05210af98 "Remove GWeatherTimezone" says:
    
    > GWeatherTimezone can be replaced by GTimeZone, which has been available
    > since GLib 2.26.
    
    It is true that GTimeZone itself was added in 2.26.  However, this
    library uses g_time_zone_new_identifier(), which was added in GLib 2.68
    as a replacement for the deprecated g_time_zone_new().
