[bug#51534] [PATCH v5] gnu: Add smplayer v21.10.0.

[Attila Lendvai <attila@lendvai.name>]

* gnu/packages/video.scm (smplayer): New variable.
---

v5 moves smplayer below mvp.

as for PATH: it uses some heuristics to find the media player backend
binary (Helper::findExecutable), so patching it is not trivial. i
think it's more resilient to future changes to wrap it and set the PATH.
