gtkplacessidebar: add new other locations with flags signal

We weren't using the open flags on the other locations signal, which
makes impossible for applications like nautilus to act in the same
way that for any other location where the user can choose between
opening in the current view, in a new window or in a new tab.

Add a new signal with an open flags parameter and deprecate
the other-location signal.
