gtkimmodule: make match_backend() query

…the wayland registry.

Wnen _gtk_im_module_get_default_context_id calls
match_backend (context_id) and the default GdkDisplay
is wayland, match_backend() should return TRUE only if
gdk_wayland_display_query_registry (display, "gtk_text_input_manager")
returns TRUE.
