keyboard-test: Use wl_display_roundtrip() instead of yield()

As for button-test, a wl_display_roundtrip is sufficient here.  The
yield() between wl_test_activate_surface() and wl_test_send_key() is
also not needed, since the two requests will arrive at the server in
order, and will activate the surface first, then send a key event.
