hotplug-sniffer: fix double free when setting D-Bus return value

Browse Source 
g_dbus_method_invocation_return_value() adopts a floating reference,
so we don't also need to unreference it; fix by replacing the code
using a more compact form using the ^ convenience character in
GVariant type specifications. (Thanks to Ryan Lortie for the
suggestion.)
