modules: remove bandlimited "audio resampler"
cf. 9c740613
Furthermore, it is probed as an "audio resampler" but won't load if
fmt_in.audio.i_rate == fmt_out.audio.i_rate
causing this module to be
never loaded.
"audio resampler" change the rate live. "audio converter" convert the fixed samplerate.
This module should have been an "audio converter".
