Remove audio/soundtracker

Starting this app spews numerous GLib-GObject-WARNING and -CRITICAL,
Gtk-WARNING, Pango-CRITICAL and Gdk-CRITICAL messages before dying right
away:

$ soundtracker

We package 0.6.8 and http://soundtracker.org says this:

Last release (GTK+ 2): v1.0.1 (29-Jul-2020)
Development / maintenance (GTK+ 2): Git master
More or less functional GTK+ 3 port: Git gtk3 branch
Last release for GTK+ 1: v0.6.8 (25-Feb-2006)
The rest of this web site is mostly out of date.

So we're massively behind with a broken port that won't see updates.
Id' say interested users may port newer versions (once they're stable).

It also requires Python 2.

Objections? OK?
