audio: remove unreferenced af_lavrresample
This filter wasn't referenced anywhere and thus was dead code. It should have been in the audio filter list in user_filters.c. This was intended as compatibility wrapper (to avoid breaking old command lines and config files), and has no real use. Apparently I forgot to add it to the filter list (did I even test this shit?), and so it was rotting around for 1.5 years doing nothing (just like myself). Note that users can just use the libavfilter provided filter to force resampling, just that it has a different name and different options. There's also af_format to force inserting auto conversion through the internal f_swsresample filter.
