Andreas Rheinhardt c59398970b avcodec/libmp3lame: Avoid copying data, allow user-supplied buffer ...

The libmp3lame encoder already uses an internal buffer, so that the
packet size is already known before allocating the packet; therefore
one can avoid another (implicit) intermediate buffer by switching
to ff_get_encode_buffer(), thereby also supporting user-supplied
buffers.
