Fix no output when ibus-daemon is running on another display.

Fix no output when ibus-daemon is running on another display.

Using ssh -X or another display, the hostname and display numbers
can be different between the GTK clients and ibus-daemon.
This patch fixes the output:
"Events queue growing too big, will start to drop."

I think ibus_get_address() is not a light way to detect it. Especially use it in
filter_keypress(). Maybe it is better to use it in daemon_name_appeared().
