Limit supported gweather to < 3.5.

gweather-3.5 introduces API changes we do not yet support.

A patch for gweather-3.5 support exists in bug 672805, but since our
policy forbids requiring unstable libraries, gweather-3.4 support must
be retained until GNOME 3.6 is released.  gweather-3.5/3.6 support will
remain optional until 3.7.1.
