media-libs/phonon-gstreamer: conquer!

Holy shit that was hard.  This fixes phonon-gstreamer to actually work.

Not sure why it stopped working -- maybe some upstream change in the
phonon buildsystem code, or as a consequence of having dropped various
overlay builds with wrapped executables for upstream alternates that
lack them.  Anyhow this gets 'er done.
