Subject: [PATCH 3/6] gnu: Add python-mpv.
Date: Wed, 27 Jul 2022 21:00:25 +0200

Author states that the license of the library is inherited from libmpv,
which can be either GPLv2 or LPGLv2.1. That's why the package's license is
set to be the same as mpv's.

One of the tests had to be disabled because it would neither fail or pass,
blocking all other tests from running and the package from finishing its build
process. I have no clue on why it happens.

Rarely some tests fail without any apparent reason. This is possibly related
to: https://github.com/jaseg/python-mpv/issues/209

Also add copyright.

* gnu/packages/python-xyz.scm (python-mpv): Add variable.
