Bug#971325: renpy: uses deprecated libavresample

Dear maintainer,

renpy currently Build-Depends or Depends on libavresample-dev. The
ffmpeg developers consider libavresample as obsolete and replaced the
library with libswresample. Please switch renpy to use libswresample.

Note that this switch will require changes if renpy doesn't already
have support for libsvresample.

Cheers
