[bug#64732] [PATCH v4 1/2] gnu: Add python-ffmpeg-python.

[Parnikkapore]

* gnu/packages/python-xyz.scm (python-ffmpeg-python): New variable.
---

Here's a v4 that hardcodes and no longer propagates ffmpeg. One of the tests 
check the
command to be run, including the ffmpeg command used, so that test has to be 
patched too.
