The mp3dec plugin needs to find the mp3 parser in /usr/lib, otherwise
it cannot load:
(gst-plugin-scanner:2636): GStreamer-WARNING **: Failed to load plugin
'/usr/lib/gstreamer-0.10/libmfw_gst_mp3dec.so':
lib_mp3_parser_arm11_elinux.so.3.1: cannot open shared object file: No
such file or directory
This is different from the other parsers, which the aiur_demux plugin
loads using dlopen() after reading their location from
/usr/share/aiur_registry.arm11.cf
