Drop the mpegvideo dependency for svq3 in configure.

Unused buffers scratchpad and temp have been dropped too.

This is done to disentangle ER from mpegvideo. In order to use a
classic Picture, callers can use ff_mpeg_set_erpic() or use a custom function
to set the fields. Please note that buffers need to be allocated before
calling ff_er_frame_end().
