Resolves: rhbz#1326304 cannot detect loss of wayland clipboard ownership

gtk_clipboard_get_owner always returns what you set with
gtk_clipboard_set_with_owner and that doesn't change if some other
application takes over the clipboard

The "owner-change" signal doesn't contain any useful data under wayland,
and doesn't fire when you'd expect either, just when the app becomes
active or gets focus or something like that. So you get it when you
do have the clipboard and when you don't, so that's no use either to
detect loss of clipboard ownership

So, forget about clipboard ownership, and always take the data to
be pasted from the system clipboard, so when we are pasting from ourselves
its "paste"->m_aSystemContents->gtk->"copy"->m_aOurContents

Undoubtedly something else will break now
