Subject: 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.

Origin: upstream, 3.22.30, commit:6e2d14037cea356638a9bea7b611cbe23bc90b47
Bug: https://gitlab.gnome.org/GNOME/gtk/issues/114
Bug-Debian: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=893696
