cheese_camera_device_monitor_new freezes the whole panel when opening for a couple of seconds if external camera is connected. This is not acceptable. Probably it is bug in kernel. Let's use GAsyncInitable if available. Bump the cheese dependency accordingly. https://bugzilla.gnome.org/show_bug.cgi?id=783789
