types/wlr_xdg_output_v1: Fix wl_output.done bug.

Browse Source 
If the client binds to version 3 of zxdg_output_v1 and version 1 of
wl_output no wl_output.done or zxdg_output_v1.done event is
emitted [1].

Also no wl_output.done event is emitted when version 2 or lower of
zxdg_output_v1 is bound to.

Add a version check to output_manager_handle_get_xdg_output so that no
wl_output.done event is emitted when using version 1 of wl_output and
version 2 or lower of zxdg_output_v1.
