backend: Tear down in dispose() instead of finalize()

This means backend implementations can have more control of the order of
how things are destroyed. To be precise, this will, in the next commit,
allow us to destroy the logind integration after the clutter backend
thus the libinput owning seat, that uses the logind integration to
release input devices.
