Follow EasyEffects' links to Bluetooth sinks too

EasyEffects plays into Bluetooth headphones through the same direct port links as into a card, but only alsa_output targets were followed, so with headphones on the keys fell back to the settings file -- which can still name the speakers -- or to easyeffects_sink. Match bluez_output sinks as well, and compare the configured device name literally rather than as a regex.
