    Use `gio open` instead of gvfs-open as a fallback when possible
    
    This also requires GLib 2.50, which should be a perfectly reasonable
    by now since that's shipped by Debian Stable but turns out it's not
    yet in the latest Ubuntu LTS (Xenial, has GLib 2.48), so don't raise
    the version of the dependency and just use gio or gvfs-open depending
    on the version of GLib available.
