[builtin] fix activatewindow if directory path differs

After #5081 the built-in "activatewindow" does not work if you stay for example in the video window and you want to activate the same window with a different path.
This fixes the issue by comparing the directory path of the current active window with the given directory path of activatewindow.

[PiSink] Dual audio support

The Pi supports dual audio in omxplayer, where the gpu outputs audio to
both hdmi and analogue connections.

With dvdplayer being more usable on Pi now, there are frequent requests
for this functionality through the Pi Sink.

This removes the gui setting for "dual audio" and creates a new sink
output for dual audio. It add support to the Pi sink and makes omxplayer
use the new setting.
